Ubuntu 25.10 Replaces sudo With a Rust-Based Equivalent

Ubuntu 25.10 will replace the traditional sudo command with sudo-rs, a Rust-based equivalent developed by Trifecta Tech Foundation. The new implementation leverages Rust's memory safety guarantees to eliminate vulnerabilities common in C-based software, including null pointer dereferences, use-after-free errors, and data races. While sudo-rs is designed as a near drop-in replacement, some less secure features like LDAP distribution of sudoers files won't be supported. Users can currently install sudo-rs alongside traditional sudo for testing, and Canonical plans to keep the original sudo available in archive repositories for those who prefer to roll back.
