Januscape and Bad Epoll: Two Linux Flaws That Let One Customer Take Over the Whole Server
Januscape (CVE-2026-53359) lets a guest VM escape to the host and take over co-tenants; Bad Epoll (CVE-2026-46242) lets any unprivileged user reach root with a near-perfect exploit. Both are patched upstream and in AlmaLinux, and for both the only fix is a new kernel and a reboot.
