Seven Stable Kernels Released with Critical Security Fixes

By Zayden R., July 5, 2026

Greg Kroah-Hartman has rolled out seven stable kernels, addressing security flaws in IPv6 and KVM. These updates patch vulnerabilities that could allow container escapes and use-after-free exploits.

In a significant update for the Linux community, Greg Kroah-Hartman has announced the release of seven stable kernels: 7.1.3, 6.18.38, 6.12.95, 6.6.144, 6.1.177, 5.15.211, and 5.10.260. This release is particularly noteworthy for its inclusion of critical security fixes. Among the patches is a fix for a vulnerability in the IPv6 code, introduced in kernel version 6.0, identified as CVE-2026-53362. This flaw could potentially allow attackers to escape containers and gain root access, raising significant security concerns.

Another critical fix addresses a use-after-free bug in the Kernel-based Virtual Machine (KVM), CVE-2026-53359, which has been lurking since the 2.6.36 kernel release. This type of vulnerability can lead to system crashes or unauthorized access, making its resolution a priority for system administrators and users alike. The importance of these updates cannot be overstated, as they close loopholes that could be exploited in real-world scenarios.

Each of these stable kernels comes with a host of other fixes and improvements, underscoring the ongoing commitment of the Linux community to maintaining robust and secure systems. Users running any of the affected kernels should prioritize these updates to ensure their systems remain protected against these vulnerabilities.
