Recent Linux vulnerabilities like Dirty Frag, Copy Fail, and Fragnesia highlight a growing trend of AI tools rapidly discovering kernel-level security flaws, with Linus Torvalds noting that bugs are now being publicly analysed within hours of being patched. The mean time to exploit vulnerabilities has shrunk dramatically — turning negative, meaning exploits often appear before patches do — and duplicate AI-generated bug reports are burdening already stretched maintainers. Experts stress that Linux hasn't become inherently less secure, but that AI's superior bug-detection capabilities demand greater security vigilance from administrators, including enforcing stricter security policies like SELinux in restrictive mode.
