COMSEC presented two papers at USENIX Security 2024 this month. Cascade shows that generating highly randomized but valid programs is highly effective in finding bugs in open-source RISC-V CPUs. In fact, it finds more bugs than all previous hardware fuzzers combined! ZenHammer shows how one can trigger bit flips from AMD Zen-based CPUs. ZenHammer triggered the first publicly known DDR5 bit flips from an AMD Zen 4 CPU!
