New "Bad Epoll" 0-Day Vulnerability Allows Root Access on Linux Servers & Android Devices
Source: https://t.co/XI9KBMFmuh
A newly disclosed Linux kernel flaw dubbed "Bad Epoll" (CVE-2026-46242) allows an unprivileged local user to escalate to root on Linux servers, desktops, and Android devices by exploiting a race condition and a use-after-free (UAF) in the kernel's epoll subsystem.
Bad Epoll is a UAF vulnerability in ep_remove(), which clears file->f_ep under file->f_lock but continues using the file object inside the critical section during hlist_del_rcu() and spin_unlock().

A newly disclosed remote denial-of-service exploit dubbed "HTTP/2 Bomb" targets the default HTTP/2 configurations of the world's most widely deployed web servers, nginx, Apache httpd, Microsoft IIS, Envoy, and Cloudflare Pingora, enabling a single attacker on a home internet connection to exhaust tens of gigabytes of server memory in seconds.
Chaining two techniques that have individually been known to the security community for nearly a decade: an HPACK compression bomb and a Slowloris-style connection hold.
