New "Bad Epoll" Linux Kernel Flaw Lets Unprivileged Users Gain Root,
Hits Android
https://thehackernews.com/2026/07/new-bad-epoll-linux-kernel-flaw-lets.html
A newly disclosed Linux kernel flaw called Bad Epoll (CVE-2026-46242)
lets an ordinary user with no special access take full control of a
machine as root. It affects Linux desktops, servers, and Android, and a
fix is out.
Bad Epoll is a "use-after-free" bug. Two parts of the kernel try to
clean up the same internal object at the same time. One frees the memory
while the other is still writing into it. That brief collision lets an
attacker corrupt kernel memory, then climb from a normal account up to root.
