The Linux Kernel is Falling Apart.

A wave of universal local privilege escalation (LPE) vulnerabilities in the Linux kernel is being analyzed, including copy-fail, dirty frag, and bad epoll. Historically, bugs of this severity appeared once every 5-10 years (e.g., Dirty Cow, Dirty Pipe), but AI-assisted vulnerability research is accelerating discovery, with two appearing in a single week. The bad epoll bug exploits a use-after-free race condition in the epoll syscall with such a tight window that even ASAN and AI tools like Mythos failed to detect it — it was found manually by a human researcher. The broader trend is described as a 'great backlog clearing' where dormant vulnerabilities are being surfaced faster due to AI-enabled pattern recognition. The post briefly addresses whether Rust would have prevented these bugs, concluding yes in theory but noting the practical difficulty of writing kernel code in Rust.
