Cascade: CPU fuzzing via intricate program generation
Cascade is a RISC-V CPU fuzzer that generates valid , long and complex programs, and relies on a termination cascade-effect for bug detection. It detected 37 new bugs (29 new CVEs) in 5 RISC-V CPUs, which is more than all the existing fuzzers, combined. You can read a paper we wrote on Cascade here and try it out here…
