Multiple vulnerabilities have been discovered in the Xen hypervisor, which could result in privilege escalation, denial of service or information leaks.
With the end of upstream support for the 4.11 branch, the version of xen in the oldstable distribution (buster) is no longer supported. If you rely on security support for your Xen installation an update to the stable distribution (bullseye) is recommended.
For the stable distribution (bullseye), these problems have been fixed in version 4.14.3-1~deb11u1.
We recommend that you upgrade your xen packages.
