A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code includes a specific x86 instruction sequence that would not be generated by compilers.
SiliFuzz - Fuzzing CPUs by proxy
What is SiliFuzz
SiliFuzz is a system that finds CPU defects by fuzzing software proxies, like
CPU simulators or disassemblers, and then executing the accumulated test inputs
(known as the corpus) on actual CPUs on a large scale SiliFuzz is a work in
progress, please refer to the
