TWO serious vulnerabilities in the Linux kernel, CVE-2026-46242 (Bad Epoll) and CVE-2026-53362, have been identified with public proof-of-concept exploit code available. Bad Epoll allows an unprivileged user to gain root access through a use-after-free condition, while the IPv6-related flaw enables escalation from a container to host root on RHEL and CentOS 10. These vulnerabilities expose critical attack vectors across various systems and have been linked to a recent incident where a Debian server was compromised. Both issues have fixes available, and users are advised to update their systems accordingly.
