MPS-Fuzz: An Enhanced Fine-Grained Fuzzing Based on Units With Multiple Inputs and Outputs
- Published
- Record updated
Summary
Researchers propose MPS-Fuzz, a fine-grained coverage method for edge-coverage-guided fuzzing that builds on basic block units with multiple predecessors and successors. It adds a separate bitmap to track MPS unit coverage and is implemented on AFL. Across 16 benchmarks from FuzzBench and Unifuzz, after 24-hour runs it explored 9.6% more edges and found 25.7% more bugs than AFL, and it also found a previously unknown bug in a real-world program that received a CVE.
