Rust in the Linux kernel enhances memory safety, a key focus in development. Launched in 2021 by Miguel Ojeda, Rust for Linux aims to reduce vulnerabilities in new drivers and modules, not replace the entire kernel.
New Rust Code in Linux Kernel
Rust reduces memory safety bugs, data races, and logic errors, making it ideal for kernel development.
It simplifies writing drivers and modules with modern abstractions and enforces documentation for APIs, safety checks, and ‘unsafe’ blocks.
Rust was officially merged into the Linux kernel in October 2022, with companies now dedicating engineers to its development.
Rust integration in Linux is expanding across subsystems, with drivers like PHY, Null Block, and Apple AGX GPU in development.
The Linux 6.13 merge added Rust misc driver bindings, paving the way for more Rust drivers. Greg Kroah-Hartman sees this as a turning point for adoption.
The next merge window may bring PCI and platform drivers, further strengthening Rust’s role in Linux.
With increased security benefits, support from Miguel Ojeda, and backing from the Alpha-Omega project, Rust for Linux is shaping a safer kernel future.
Kernel maintainer Jonathan Corbet confirmed Rust’s viability, highlighting its importance for Linux’s future.
