Linux runs the world’s data centers, servers, and embedded devices. It powers Android phones by the billions. Yet for decades, its core—written mostly in C—harbored risks. Memory bugs. Crashes. Security holes. Developers fixed them reactively, patching after failures hit. Then came Rust. Rust doesn’t patch. It prevents. Compile-time checks block invalid memory access, forgotten cleanups, data overwrites before code even runs. MakeUseOf spotlighted this shift: C’s power built Linux, but its dangers made systems fragile. Rust refuses dangerous code outright. “Rust looks at that entire mess and goes, ‘Absolutely not,'” wrote author Roine Bertelson. If code might mishandle memory, it won’t compile. Kernel teams added Rust support in 2022. Not to rewrite everything—no one’s touching the vast C codebase. Instead, new drivers and risky components get Rust first. Why drivers? They’re crash-prone, often from third parties. Rust slashes those failures. Fewer freezes. Fewer exploits. Fast-forward to 2026.…
