Rust Researcher Builds AI Pipeline to Test 900 Vulnerability Hypotheses Across Crates and Linux Kernel
Sergey Gordeychik developed the rust-in-peace research harness that combines multiple LLM agents, traditional SAST tools, and dynamic verification to hunt for memory-safety, logic, and API misuse issues in Rust code. The system generates independent hypotheses, attempts to refute them with separate agents, then validates survivors through fuzzing, protocol tests, or container execution. Starting from the Damn Vulnerable Rust Application, the pipeline was expanded to popular crates including x509-parser, h2, and lopdf, ultimately producing a Linux kernel patch. Experiments showed that three parallel analysis passes yielded 20 confirmed findings after triage, with nine appearing in all passes. The work also highlighted how models can produce convincing but false positives when context such as dependency checks or call order is missing. Gordeychik presented the approach at ZeroNights under the title Rust in Peace: How to Raise Your Own Pet Mythos.
