Ubuntu 26.10 completes its migration of core utilities to Rust-based uutils, resolving prior TOCTOU security vulnerabilities that had delayed the switch for commands like cp, mv, and rm. Canonical began its "oxidising" initiative in 2025, funding Rust software development and gradually replacing foundational C components with memory-safe Rust alternatives.
Background
Canonical has been progressively replacing C-based system utilities with Rust implementations since 2025, starting with sudo in Ubuntu 25.10, as part of a broader effort to improve OS-level security through memory safety.
