<p>Hot on the heels of the <a href="https://lwn.net/Articles/1105899/">previous two stable kernels</a>, Greg Kroah-Hartman has announced the release of the <a href="https://lwn.net/Articles/1105903/">7.3.3</a>, <a href="https://lwn.net/Articles/1105904/">6.18.62</a>, <a href="https://lwn.net/Articles/1105905/">6.12.116</a>, <a href="https://lwn.net/Articles/1105906/">6.6.162</a>, <a href="https://lwn.net/Articles/1105907/">6.1.192</a>, <a href="https://lwn.net/Articles/1105908/">5.15.225</a>, and <a href="https://lwn.net/Articles/1105909/">5.10.274</a> stable kernels. Each one only contains fixes for three use-after-free vulnerabilities announced today by the Xen security team.</p> <p>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 (<a href="https://lwn.net/ml/all/E1xPLfb-0000000A5rj-1W0D%40xenbits.xenproject.org/">CVE-2026-100080</a>, <a href="https://lwn.net/ml/all/E1xPLfh-0000000A5vb-11J3%40xenbits.xenproject.org/">CVE-2026-100082</a>), and one may allow privilege escalation as well as a DoS of the host machine (<a href="https://lwn.net/ml/all/E1xPLfe-0000000A5tc-0wMP%40xenbits.xenproject.org/">CVE-2026-100081</a>). Users should, of course, upgrade if they are using Xen.</p> <p></p>
