"Just Use Rust": A Best-Case Historical Study of Open Source Vulnerabilities in C (PDF)
We identified 68 prominent open source projects with C code, collected their vulnerability history data, and used their CWE designations to explore a best-case speculation on how many vulnerabilities might have been prevented with Rust. We estimate that 58.2% of historical vulnerabilities in our selection of open source C projects would have been virtually impossible in Rust.
