you have a good fit to the and the the and you know so I I I I I I I hand-labeled and talk about some to give exploitation and I hope I'm not too much about I find by and but some are like adults of on the box Our would need to exploit the back and some techniques how to get can always occasionally not to just stand up like the of the soul is basically
outline how understanding the farm odd Greek was the houses story but to start or finding the box and if the if and where do it on some different between the URL our previous public to give higher research and hours special exploitation and then being tuned got out along exploiting can alter but scanlines agrees on ends Our mother bypass some mitigations auditing implement it's and it some of them are importantly it's nuts and thing with the its the so had
lots of meaning is that who we are our yeah King Dean amazing how China shining yeah and so they're doing reading circuit search and Haar-like changes or additions and security and that's society in our drink embodies like owned poverty books a system call experiments also actively contributing to to the collating for example the input roots and so the join goes on all about think of addition operation for the 0 and we show some difference from they such informal informals books called tools or Francis we've result of CDs and it's nearly some techniques
and so on I and we've disposable to present single on conferences about some general issues about some design and sell the bypass parser mitigation somebody'll some in the URI now we'll show how to lose its in practice so can study
follows the the face tie with gift of I am but from Wikipedia and this the sum our system for all time showing them formants that's forming and I was more of a of focusing on how to explain it out executes our blacks and for me those are MOS important some the isolation and that's it so legal tool which you can use Ottawa iterator rights Granell by on the bomber change directions or it can use it sounds it's feature that somehow it can corrupt spatial memory under the sectors in memory counts so you could you block and it can mean in fact highly it's the same annotator rights and that's enough for us our debates other things so I think it's I use lasing Pennsylvania 1001 town more research into the events in a more big amounts to Canada's materials but I hope that you bit family of its and for exploitation of the sets its most important so that you can be in the speedy if you can achieve some reader right in somewhat con OWL and some of its conditions and so about so as to give our stand-alone 2050 if me because of the bone and Our my legal possesses a will 40 give housing and he's built some little parser and some new idea and so father on for about 3 weeks and beginning in the form the font so the bikes and some of the 3 of them both explicable that's unfortunately not that much time to played it since I started playing I think freaks before quantal and so 1st of IT image I that's more than most of our fixed in best using how that might be 1 as before and students graduate from microsoft so that it was not a pleasant and trying to measure for us money formants hardly spoon on all those models much patched and we can use it but you know so I like we're challenging and promptly now we have some more but the but if you but it's our it's you know to least
future and so the 1st meeting held in the box and stuff public transitivity of falls that sign up in Paris a sessional abuse the yet to be polishing sections are going to get some chemical is usually topics for its on in bookie use or can it be the that's the the right goes back in building on the block we follow about the state of the Commission and to use you need some would say in free fall are the section 2 of the 4 bytes doing not going to get is back but after states you cannot so far and it's not raining cocaine some of them cooperates at the back you just to some all fall and that's it and
that's of these stops and and the beginning of the some pressures and so I will 1st 1st name 1st thing units when you want exploits the deities are you only needs to find a way out about the PDF formats and for this is some of the tools available that PDF file to the examples for Python and also needs on his but found in fact they use for that fireman and some planes are the book the boys of the and pass the information from DTF in human edible and it's fairly clear aim and you can see all of that tables of properties in PDF and filigree and it's and tells needs you also need on rate in the plantation abouts sections of other formats ourselves and 2 ends
that's the only 1 minimize the DF on because build some the also can have you know the final say sections so the from society are the tables and sell something properties you want to minimize that file and he guilt as many as many sections belief this is pen and then candid and for that you need to know where the formats and you probably don't it's by our build sampling tools for it and you and so on so many most file but some venue configured back and then you can cancel easier to get sigh into the with the problems and for 1 of the few but the loss the yielded to you don't call that psi that's weak variable the chicken back and then it still because a culties horror falling toward I'll before Hopper east but the the channel and the new the human touch of of pages these regional marketing can overlook panic so it can be a problem and its internal the bachelor pages it can be in a of because it's you're not supposed to FL of control from his amounts in the kernel the and divorcing that science labeled intact from managed to get back to you so they will change in from the top from from this the if any more and any another books on how to lead his back the but OK we'll do it and we just I can download it
propelling hints strategy the job out our dependent so in constant on this so if a link for the pages oscillating in C that are found in those who have found introducing for 64 owned by forming the with in yield gaps in 64 bits the space but these gaps are only and comes to warm start the it's only the use in between those between the stations and you have our lives on at the visibles Neufeld of walls but i'm but fortunately for us to explain 50 years own social space and that means that some for example and 64 bits you have because of the gaps it's early an efficient by the polls spring but then comes the occasional that it's a it's a special if the both paintings this police still affect you and you can use
it in the in the in but for its you need to find some ways your objects our from which were falling from the useful and in our case the recessional OK so we don't look at more and more about its entries accomplishing breakpoints on now session pool elements from visible also you like to go into the big pools because in the People's Armed if mom and expose going not to minimizations and mental and mitigation see single monitor and that used also being in that leaf our these can informations and being on bench begin our look closely and so on and that creates India being and we'll died them and each coping itself of candidates which are allocating though big big pool memory which was that created in part to be up and it was very good candidates because then look and the communication and then at the end we see that the many CreateBitmap you can mean our proper just height of items that you can control the size of the of the the book and opened allocated from the them that good the the so that's very good some because
sound then we can choose OK will be excised so they're being stuck in in their own meager locations and at the same time it will be insatiable this is our did have and it will start earlier far with features on its of saying feature from a point the field our because they customization from it's not the place to be calls every I don't I believe that some are how working but if it's there in those St. are envisioned the city and so that means that you can make an hour mournful layouts and you can make calls inside and you can prepare them space for a TTS and umbilical and solicit those King some social polling simple easily it's still prolific not that a cue for although our mitosis but other space but particles in the but called pull it silly effective and this means minimal the base of the pole you can also part of it and use it but as you can and it's also a new filling in overlooking a local keep on exalted polar expiable from them to the most indirectly it's it's article feature and
that means you can handle on developed over 4 and the that's how babies and you have for legal feature that you can and the blackouts and so on on the new that's euro involved all full from the old shower system anymore so easily because you can spring at the summit maps after PDF introduced the sound to the back and you're just our bodies and bitmaps and Dutch that is beaten up so you don't panic and the money feature in my it's possible is because you have 4 6 4 bits of space along the new some speech not meeting because for example I was talking although fall on confidence and so then use 64 bit sign make other space be that he's got space and then you can now bodies lots efficient but you can do it in the you sound and the page but not this after of the celebrations and many fully loaded spending get maybe there's a space but since it before because I don't think so and can be Olympic ranking Mr. kill this offals but it's not so important that and you can Our so the he's 1 of their own our best choice is then you want to exploit something because our race condition other kind of work you can on collecting buffalo and the bathroom floater began its some techniques can which can be really useful and some
that's when comes the particle of the collective yet from back home real problems the I can go on living because because it's FIL it's the it's the and say that's OK following come from them from the the but to be able to debate site and protest control the bites so that means it's some it's awful and some other the pages in these pages of income of magnet calculations in some conditions met things invites change and mom for this you need to something because you don't own was something on change on the proposed conductive doing something for example the most size so you want to know when we know that talking and the sorrow and is also the other change and don't in make size bigger the for these kind of things if you can help on the fly offer them sometimes so there's because it let's that soaking in some conditions on the if the Mets to our are 2 modified neighboring he needs to satisfy some of our own some of those in the morning that the become like that's and some outsourcing controlled output easily be tempting that for example that's optimal sizes some media so you want to on it's a servant was 5 and want to most it down but forties are divided in that and mountain dew to make some populations and so as a set for this can be useful some some based on on on the flow graph and the conditions and the exact problem the so it's kinda getting complicated is
back because you go through many want to our patch by something in the whole In the 1st of all it's hard to meet some conditions inmates cells that's why some of some of much of the compilations so that it can poncho ladies send you out Baedal not spaces control but you can't for example the said that the highs by the the 1 or something like the song engine and for that's you have to control the memory memory effort DPFs of means you have to move out of control about that's a memory after fold after which can be a problem because you're his amounts about this money is and candles but it's a little is the true is from
1 because you can find surliness are methods especially for those you up and this move methods are for example on the sits between bits and GetBitmapBits in fact it means that you are able to read or write to canal exactly that out what reach so that means you can have on the kind and is always in the face of the new isn't as a being channel hence this illegal feature because now you can exactly that control the bites the the Kiev and say more about the on which are structure itself the very making confounded because you have found this city of this size in the header and you have also some point at the buffer and these you can partially it's fully partially from the user model to you can allocate it's on or off rates In can are from his emotes burial by great big number on the other objects and you can also sets or are it's the bite from the neighboring Tulsa by some is only the ice so in fact you have full control about that piece of memory and can and then you're able to answer most of other to hide the rights the the size of the beating up you can mean and Underwood feature is that
sound the that the head of the map
is in by state so that means that you can by city of size you have wanted the buffer of 1 that block and that's really cool because of some and the features and because many of our from this amounts I expect that OK in this memory can control that that and I can reach the place they do it's illegal for the will of consequences for you because you can at eliciting more size because we know that some of the sites you control and in all reach the size and it's not created so can change it if you can move the size reasoning or you can changed down point at about 1st Our can for example in out the DFT is doing is to use the header thought adult sex but also the 2nd Meeting of in the and for that so cells they may go that we can really begin expected but they'll be didn't in the head because it not create that explains states and so you can use it and so we you is that some as a simple a scenario the being allocate some beaten up after all it's a needle being positive yet and you want to other the but for the SVM and the amount of this size the questionably if the rights to lock and load these are some kind of buffer of sunken a pointer and so many 1 to us is the man reader writers did not In its arms gets are 6 what's the souls of the walk so for days in install cable to the 2nd big map and spray there is of all the memory and that's all you change that would change the size and do this and I walk will be points I like that to me on the fiery but the sample surely sprites so access global successful and that now you can use set or get bitmaps bits and what does it mean for you that this means that's our you grow up the 1st become up you grab just by showing that he was a size but it does a little bit but for these you can so that you the functions on this for the the map to alter the 2nd because the and by the size Our doing the minds on which means that you can take the rights to all parts of the model can memory there will and in our case the user travels because as I said that's a real snub able to that its own change down on on properties of the 1st to become there so you need to use that and therefore the map in the 1st place and being need to you this had the plot of these because of their their only these finally can of this from bitmap and that use full can only in books the and the
cell made by the panel is a powerful minutes to wrap up by the origin rules but you only have to be studying some out fall and the have let's say we cannot use some the right From the this often bytes not to sequential Duncan memory all the bytes of the almost all the bytes and then they achieve some high cwazy father think also to full kernel full rights or at the kind of memory and that's the powerful
but slowly kinda now what you wanted you know now we want to go to candle for
example the patch from that book and some of the system called the but for these you want now facing there are some kind of security some mediations introducing buying the from America's of of and so forth delegates who have some 64 age 64 bit to the space not something feature but In fact it so would cooperate 3 Fonseca the beaches and some 2nd thing is for example if others began of this this standardization our and you've also known by the folding altered memory is limited label is also a little feature new of some sober-minded supervisor-mode Texas and like the compression axes mount version is it's not simple and that's yet but hopefully frugally song about the ozone in Our play the cycloaddition the ozone taking causation the SOM and also some wonderful integrating are fact that the 4 on fall on the flow graph what and ends at the 1st of what is whether the Panel's vision of standardization that means that and then you will some model can only be at some random places serial on this disaffiliating beyond the base and be stored these models and the same applies for them from the front wheels so that means beating the different polls will be some pigeon axis that means I
if you are in trouble even then you have you should be doing shovel even when you have full text full rates and right there with the cardinal because now you have seldom gaps in kennel and the same time it's on the mice so these units freedom right the canal you owe purely afraid to touch anything because it can crash the but in fact it's and for these you can overcome this injured by some painfully back in the 2 because they butts i'm because it means that use their own uh it's a sound is solved exploited because its 2nd back just for leaking some information about out the but in fact it's when you have a right to Kremlin worrying currently you can only buy positive that using in this these features because we can use for example what is added here is eating the instructions and the books some he wanted to can no and each point on the point and you can arsenic was a reading the droughts where there are where is the model-based so only met a scarce fire ants you are not separated from the home of the gets patient the more or you can use it some on the old main how known and it's nice technique the and the
technique is also this doesn't love and the values it feels because in 2nd to give back come and do it for all other being product that every year and using for the debates and so they will use this technique in because they use the on as you your is it the section the as mu 0 OK I want because it was pointed tournament the gunwale anymore so but I was lazy who implements the find some taking graphene Pimentel these formant I'd like it's so was so looking for some on the feature out throughout world and it's seen and a fast because have some temperature and as a member of that in the past using the good article about some popular with exploitation and was but amounts in 2011 but I was for that use politics but in fact it is a fixed i in the EC some might be feature that conditioning form and then you can look at these you eat the point is from the canal from that fund them to because the only thing you need is down very it's the single public single from the is if fitted to the l and then you can aid the pointers from the candle and so and selling them taking the base of the session pool is silly problem i'm because is adversely man in this cabinet 64 bit space and can as as the than initially a problem gaps and your mind problem is to get some light the and especially when it gets session vol . us so I think it's silly game over I will show later wine yeah and big and sound at the end of reason before because of the then them addressed to the session pool you can use the default the that sound Our you're back to fully rights before for the big maps is if it is shown and except that you really the point as long sessions based you can read more and you can find tools of pro point us to the process the and that it's that you can end up the subject in top later because the you have already left for a full rewrite the canal ensues you known point us to but you process so what needs to basically just bash some token in your impetus and what's the problem it's extending goods but not with that because of goal the program to get some cannot coats execution because I think it's more serious issue and
Strogatz own system optimal distribution units felt jumping the penalty your own and 1 of them would scanned the cell is best able but toolkit something different so for example you have Theorem some function this hand values some in it and use message goal and the inside to the because you have something in this fashion it's really called and zone this talk is based on the summit of able to recall Table some there was some function pointers which is the rights that section of the mean for that OK so infects infuriating before we can just all right on this point us it will be some function because he's such a simple Siskel and you can just see the cute some cold and bicycle bias are surprise abilities but now this you can't because if introduce a what's fries remote execution dimension that means that's when you in the skull your internal and when when you want to jump to the motes quotes you know just panic because it's not told you can just the the the supervisor and privileges depend just jump in our the proviso of space so you cannot execute and code from to them the power and also the player in this is a maybe votes and able yeah surrounding knows but quantities these so if all the problems that so you have to and some yes a promise me that can surprise among quotes in want to touch some nothing is a all to be cannot because is is the user motive to read together from the user modes or some mapping from the user model can now and then you can and
at solids makes him this room on mitigation so powerful is also income initially flows it not the norm executes like although OK shells because that means that you can gold is basically they're coded up and only 1 difference is that it's not likely the executive and this time could fly can make fairly difference that between them that the and cold as now you will be on
bypass the on in this form the reordered that does that isn't being the 3 that function so the sets and get the GetBitmapBits because basically you can port some your control it's not that to panel must still you cannot say executed because if a summit being and you have also all if I said these OK because you know it's you that is a kennel but if knowledge could and then it can jump it's the it's because it's executable memory and so you can look at the you can play it's because you can now you have 4 sorry the rights of the panel and you can still use the page tables and you cannot the base tables and other debate between tree and those barriers as shown by some research not so long to on our it's also in some but the protection of some of some protection implanted for example a good chance on that it cannot you leave and surprise codes easier out there are out there to the base tables so that was kind I enforce the SMAP being so much of the candle on Windows you have with functions 6 old people and you Alcatel also are executes even in our in this friends so forking so don't to this function directly and remember that to be a full can right so we can use some as a appears for example some about some function pointer and 2 invokes the school and jumping in those functional and took it can help memory boats you have 2 problems you need so when the sound is all people and provide some out by documents 1st these you need to provide them with flakes and this like who should be free to write in the table as a constant you need down leak harm Dodgers we'll be allocated because located you just you can call the sun's Siskel and all let's say you're it addictive Excel capable and invoke it in memory but you don't know where the memories because of link them when the MCE can be a problem and to use a loss of pride that the ability is acute page the it is a good deal page the but for these you can use with Richard not treating because soccer and the user message goats and and there's a message goal I use some proposed because it can be at 1st fairly easily thrown out from the resembles 2nd thing is that some in the middle it's contains the process set them on the talk all the 1st think for think is that's for our delta hungry local is directly copied says a return to the most studies venue our worry right some function individual table 2 eggs or people you will you are able to leak delicate and vector you must OK problem OK now we can allocate memory you can make that point but you need to be also is a good people read and write and for the standard provides those likes and so as it is again the that's our 1st our 2nd argument is OK 2nd opments sees provided from resembles the further arguments East angle and many this is called the 1st argument is Engels living the good and and like I always felt by date it in the procedure which trust which stars like the sandal to can pointer and this can of pointer is provided as a 1st i Woman looms they local and that means many are able to I gets some medical reason be the translation and are translated to link cannot pointer which them into packets many looks as if like it that it's slightly favored acute you can mean the let's how effect it Europe can believe intriguing but in fact the reason so
intriguing because I think about it at all East India the rights is so on gets the mean the land on which you base pairing are great cell the windows and so for W. called dissipated as its all and so if you want to 1 and do it's no underlying goal and also because you can use In this function in
the function it is on the trick you can provide not just it 1st will not sorry right before Excel pit bull pointer but you will provide the sum of the function which returns you the 1st argument so that means then you provides I'll you don't some handle being the all the village aspects of the canal at point a and this on the talk allele bit this point of the vector you so that means that you're
menu look bingo and it provides I 2 and the user message goal you will leak their address of this mean knowing the kind of and then you can check if mendicancy when it can organize the flocking say circuit about bitable and DP-based men's our Englebert meanings and this angle you can allocate so you can change the point you can change on the point the function point at the points to exalt people and you what you allocate the be the symbol other side you want and these memory and a bit but they could table with size he wants and it will this point a big deal and a that you have read write memory in which we reduce already for Americans pointers and you can write to the spot in memory your control that the beach you can make the i jump to to that and so are equal and that's on the articles they found the feature because anyone are some can't afford think what's it's called a full what's which means that you cannot to jump OK somebody talk what's Eating point the kennel for now it is and so well let's let's the full important can on working and so that means that when you are invoking the kind of some talk all will be checked before in this address Eliza is is in summer exerts its youth about function and its can be used in some rhetorical and if it's not independent its it's things OK yeah but the facts about
effect this wonderful worked it's only in town our corpus some old and some idea of the error be but there were these scandals and so and but it's it's a and thus all this handle this he shortens error be sure and you to some extent said at the beginning but then look at the different group and that's are you can exploit some Our these people post we just also some I functions but they provide some of the function that is supposed to be called that means you can some of the change in the states of your machine and so for example a can and then you have vise of linear free the canal you can you can call for example this is total many many times you can or I disappointement times and some of the functions and so you can go step by step to the to make some tools some some model the make state he wants the week some pointers to set some memory it will be neglected will perceive some I repeat that appear you make some air we change and just single Cisco and looked eagerly all MP Chen and you gold some chemical that usual mother the it'll be more steps that if you look your change point the lose some something for you and then you will change it again you will call the kennel again and will change the context again and you will be billed times and achieved the logic and at the end this you can and hopefully get some collocates COLT execution it will be somehow complicated and you need to find somebody said functions which is saying is that for example under the null and for example that seem out taking come getting kelp execute and getting inculcated there are advantages to the Bhopal the use exactly this kind of our function function the fact that the bright just by function pointers not send me that I use their own hourly easy function that that the way they won't say will still using and will likely that it that this those functions of the military threat invites functionals modes OK that those things for me that it would be next time will be more harder but they need to find more functions due to it's more step by step is obnoxious directly for example deleting memory or just just all getting money on the 1st step but I can somehow of loading because plentiful foregut what is not exactly about the con conscious of on Contra for integrating just scare OK you from a copper-zinc with just some I think the functions is not the for the plasmon jet this objects have only for the subjective some articles is some was signals from global loading up the sum of the function of there and that length that's how them from the different objects goes some different functions which is not supposed to be culled from this object the and 2nd finger that's in the last
step OK the for example now we achieved full Canada rights real Qatar memory which regenerative writing the code table and the able to pass the that up to that memory mother files that will be down to the memory and for serving the allocates a piece of memory and using the table and the get Oracle there this function which you want the goal is not in the so CPB map
so the only somehow to jumping its and let the Fugees implanted our on but now we have so on the on the problem the then you that city if once the 1 take use mixed in this sticky thinks that the ants also makes the of our contraflow . us better policies and then you are able to I was defined as the edges and the change is that founders and then mean you over I think the 40th ocean I but no sense can and minerals the by the not normal that's easily upswing of tuned to the friends x on stick for that and optic forum on wonderful that means for example for contraflow you are it will talk later some subset of the inspections that means in the future human have can lead right you're not able to up other that can also think of the book and no control Forstic because the panic because for example to this controls that you can you can add value only only when you call something jump up or this 1 you you are not able to watch distinctly some moles or police action for example so it can solve the issue but for now it's you can view of makes this technique that the contraflow In information-centric understanding so for example it's 10 on revised and feel perceive you and being solidly down don't Pinochet's is the problem that you have fully rights and screaming at me now if also the how can I mentioned a canal so that the dual is basically call this right functions for cold this right beneath moon and and that until we just say rights that are recognized as the major will be greater it's after the start of the skull that means in the latent our quotes that means no additional checks performatives by functional to because you will that that mistake any time this then you can do it's and so in the end spend every system call angles those with scalar driver see the bolt on this something from from open driver because of the achieve that cannot right to be achieved on allocating there's a is a good a memory in being being loaded now that and the jump there and it's is over and what a
that's popping cult he I will then be doing it's not Mozart induced of operating systems in general because for them than those of the if some really good technique for for false and you can use it seemed denigrating the only thing that any component is some because ability elaborating and the technique can being fixed and small more
important most important thing is that is their own eyes on the beach the issue that you can't miss the out in the stands How of save candles you can mean at you the cannot for the occasion we just right 1 might be just or 0 to 1 and it's over but they have to be OK you have to control that the rights but you may just this 1 you can pull all the kennel because you can link don't get position Bayes address and you can use that they think of the the bitmap and you can use it so it's only in the singular said on the canal if and then you look at the
aftermath from that's for example now on this out of the box be a portable phone and now become presents all the cells become but fellow the back because it's not speaks it's saying before they say that it's a it's perfectly work and I understand that Ciliata fix that will never the same channel especially if the about DPFs but in general and speaker catalysts can be a long process but there will be many look get its in different scenario that for us in new its father abouts freaks around the 3 box if either so his father rules but it was a of and it's nuts and we do it for circuit differ from the employer birds fixing and it but the other guys are doing of much more essential you than us on the doing the disease it should be for us into it's probably wholesome now and is against units for was about at most defined in those blacks and now it's more than 3 months itself fixed so it's really a possible that all these guys have the back I don't know maybe 1 these but this on the box and I think the this kind of much of the Illini fixed this was possible and they said that exploiting this kind of box and at you you then can internal and why it's not lot because immigrants in currents were designed In the end up in court rental but if he sends an East the reactants he old say that are means of these and you have not too much care about the security staff and now it's by design some broken some you on some you introduce some indications and someone thinks it's amazing Brok's doesn't cooperates so I hope in the future it will be events maybe from scratch and not so much of it will be a sum majorities and systems and it's not the thing is that's not a good issues like reading some can I disease for an imposition pool is public and its public for 4 years and it's still you can use it and that's a big deal and so in in the
presentation i want to invite you for orients in it in the bride's is some even from the geeks you component smart devices it's the approach the rising baking he will be an 24 October and so it's all forms so when you want to win we present some research but but the both from the ice and just send out of them send us some summation and the if you think it's cool began going sites if you can pull on the smart device component cars might micro if smaller trees but if think he's school yeah really appreciate it and this will be on the trip the so this time for questions
and by hiring so you have any questions about these spent fission just off now later when the doctor OK thank them thank you and the fact the

Fachgebiet Informatik
Abstract In our recent work we targeted also win32k, what seems to be fruit giving target. @promised lu made our own TTF-fuzzer which comes with bunch of results in form of gigabytes of crashes and various bugs. Fortunately windows make great work and in February most of our bugs was dead - patched, but not all of them… Whats left were looking as seemingly unexploitable kernel bugs with ridiculous conditions. We decided to check it out, and finally combine it with our user mode bug & emet bypass. Through IE & flash we break down system and pointed out at weak points in defensive mechanism. In this talk we will present our research dedicated for pwn2own event this year. We will describe kernel part of exploit in detail, including bug description, resulting memory corruption conditions & caveats up to final pwn via one of our TTF bugs. Throughout the talk we will describe how to break various exploit mitigations in windows kernel and why it is possible. We will introduce novel kernel exploitation techniques breaking all what stands SMAP or CFG } and bring you SYSTEM exec (from kernel driver to system calc).
