Post Syndicated from jzb original https://lwn.net/Articles/1105902/

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 DoS 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.
