Greg Kroah-Hartman announced the release of seven stable Linux kernels (versions 7.1.3, 6.18.38, 6.12.95, 6.6.144, 6.1.177, 5.15.211, and 5.10.260), which include fixes for two security vulnerabilities: CVE-2026-53362 and CVE-2026-53359. These fixes address critical vulnerabilities, including a container escape vulnerability (CVE-2026-53362) that could allow attackers to gain root access on the host system, and a use-after-free bug in KVM (CVE-2026-53359) that has existed since the 2.6.36 kernel. Users are strongly advised to upgrade to protect against potential exploitation. CVE-2026-53362 was introduced in kernel 6.0 in IPv6 handling, while CVE-2026-53359 is a use-after-free bug in KVM present since kernel 2.6.36. Each stable kernel also includes numerous other fixes throughout the tree.
