RustMizan - Function Localization: leaderboard

RustMizan (2026) evaluates LLM agents with shell access on 173 compilable crate-, file- and function-level Rust variants built from 42 RustSec memory-safety CVEs. This board is the micro-averaged F1 of the vulnerable functions the agent names, in percent; higher is better.

Metric: Micro-averaged F1 (%) of the predicted vulnerable (file, function) pairs over the 173 compilable crate-, file- and function-level Rust variants of 42 RustSec memory-safety CVEs, unmutated, each analysed by a ReAct agent with shell access in an Inspect sandbox that returns a structured JSON verdict; higher is better.
