Hot on the heels of the previous two stable kernels, Greg Kroah-Hartman has announced the release of the 7.3.3, 6.18.62, 6.12.116, 6.6.162, 6.1.192, 5.15.225, and 5.10.274 stable kernels. Each one only contains fixes for three use-after-free vulnerabilities announced today by the Xen security team. Two of the vulnerabilities could allow an attacker to cause a denial of service (DoS) for the entire Xen host machine with possible information leakage (CVE-2026-100080, CVE-2026-100082), and one may allow privilege escalation as well as a DoS of the host machine (CVE-2026-100081). Users should, of course, upgrade if they are using Xen.
