Everybody panic!" and "By priming the BPU of the CPU a malicious process can read out of bounds memory via speculative code execution". This talk comes with a side order on "Understanding CPU architecture" and "Managing security vulnerabilities". Jens Neuhalfen https://programm.froscon.de/2018/events/2101.html
