Name of the Vulnerable Software and Affected Versions Xen versions prior to 4.13

Description An issue in Xen allows Arm domU attackers to cause a denial of service through an infinite loop involving a compare-and-exchange operation. This can be exploited to disrupt service.

Recommendations For versions prior to 4.13, update to version 4.13 or later to resolve the issue. As a temporary workaround, consider restricting access to the compare-and-exchange operation to minimize the risk of exploitation.
