The paper proposes MorFuzz, described in the abstract as a processor fuzzer for discovering software-triggerable hardware bugs. Its central approach is to use runtime information to generate instruction streams with valid formats and meaningful semantics. [MorFuzz technical approach]

According to the abstract, MorFuzz introduces a new input structure for multi-level runtime mutation primitives and uses an instruction-morphing technique to mutate instructions dynamically. The work also extends a co-simulation framework across microarchitectures and introduces state synchronization to reduce implementation differences. [MorFuzz techniques]

The evaluation reported in the abstract covers three open-source RISC-V processors—CVA6, Rocket, and BOOM—and reports 17 newly discovered bugs, with 13 CVEs assigned. [MorFuzz evaluation]
