Bad Epoll (CVE-2026-46242) is a race-condition use-after-free in the Linux kernel epoll subsystem that enables local unprivileged attackers to escalate to root on affected Linux and Android systems; a reliable proof-of-concept exploit exists (reportedly ~99% success on tested systems) and patches are available — administrators and users should apply updates immediately.
