Bugs Rust won't catch
In April 2026, Canonical disclosed 44 CVEs in uutils—the Rust reimplementation of GNU coreutils shipped by default in Ubuntu 25.10—uncovered during an external audit ahead of the 26.04 LTS release. These bugs, which were not caught by Rust's borrow checker, Clippy lints, or Cargo Audit, span categories including TOCTOU vulnerabilities, UTF-8 handling errors, process-aborting panics from unwraps, ignored error states, behavioral divergences from GNU coreutils, and post-chroot library loading risks, highlighting gaps in Rust's safety guarantees for systems code interacting with the Unix environment.
