Keynote: Rust in the Linux Kernel: A New Era for Cloud Native Performance and Security
Talkat KubeCon + CloudNativeCon Europe 2025 · on Wednesday, 2025-04-02· at 09:55· Level 0 | ICC Auditorium·
summary
Linux kernel adds Rust to reduce reviewer errors by making the compiler enforce lifetimes, locking and error checks, replacing repetitive C unlocks and frees with guards/scoped references so reviewers see simpler diffs. Kernel still contains 34 million lines of C but production servers run ~2 million lines of C and 25,000 lines of Rust. One new GPU driver is written in Rust, Rust crashes fail safer (panic vs remote exploit), and maintainers report fewer manual unlock and unchecked-return CVEs.
