Ubuntu 25.10 will replace the traditional C-based sudo command with sudo-rs, a Rust rewrite that maintains the same user interface while providing enhanced memory safety and security. The change aims to prevent buffer overflow and use-after-free vulnerabilities through Rust's compile-time memory checks. Users won't need to change their workflow as sudo-rs is a drop-in replacement, though some lesser-used features won't be implemented. Canonical will keep the original sudo available for those who need to revert, and the transition serves as preparation for the Ubuntu 26.04 LTS release.
