Stable Linux kernel updates close two critical vulnerabilities
Translated by a model; the original is in Russian.
Greg Kroah-Hartman has announced the release of seven stable Linux kernels: 7.1.3, 6.18.38, 6.12.95, 6.6.144, 6.1.177, 5.15.211 and 5.10.260.
Two security vulnerabilities
A number of the released kernels fix a vulnerability in the IPv6 implementation (CVE-2026-53362) that had been present since version 6.0. This flaw potentially allowed an attacker to break out of a container and gain root access to the system.
The second vulnerability that was fixed is a use-after-free condition in the KVM subsystem (CVE-2026-53359). Notably, this bug had been present in the kernel since version 2.6.36, meaning it had gone unnoticed for many years.
Other changes
Beyond the security fixes, as is usual for stable releases, each of the seven kernels includes a set of various fixes spread across the source tree.
Users are advised to update their installed Linux kernels as soon as possible, especially given that one of the vulnerabilities affects container isolation and the other concerns the KVM hypervisor.
