Technical context of MorFuzz

MorFuzz is described as a processor fuzzer intended to efficiently discover software-triggerable hardware bugs. Its core idea is to use runtime information to generate instruction streams with valid formats and meaningful semantics. [C4]

The paper states that MorFuzz introduces a new input structure for multi-level runtime mutation primitives, uses an instruction morphing technique to mutate instructions dynamically, extends co-simulation across multiple microarchitectures, and uses state synchronization to reduce implementation differences. [C5]

In evaluation, MorFuzz was tested on three open-source RISC-V processors—CVA6, Rocket, and BOOM—and discovered 17 new bugs, with 13 CVEs assigned. [C6]
