Overview

Jinyan Xu is listed as an author from Zhejiang University on the paper “MorFuzz: Fuzzing Processor via Runtime Instruction Morphing enhanced Synchronizable Co-simulation.” The paper appears in the Proceedings of the 32nd USENIX Security Symposium, held August 9–11, 2023 in Anaheim, California, USA.

Research context

The cited paper presents MorFuzz, described as a processor fuzzer intended to efficiently discover software-triggerable hardware bugs. According to the paper abstract, MorFuzz uses runtime information to generate instruction streams with valid formats and meaningful semantics. The work introduces a new input structure for multi-level runtime mutation primitives, an instruction morphing technique for dynamic instruction mutation, and state synchronization for co-simulation across microarchitectures.

Evaluation reported in the paper

The MorFuzz paper reports evaluation on three open-source RISC-V processors: CVA6, Rocket, and BOOM. The abstract states that the evaluation discovered 17 new bugs, with 13 CVEs assigned.
