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 LoadExcl or StoreExcl operation. The vulnerability is related to the execution of a cycle with an inaccessible exit condition, which can be exploited by an attacker to disrupt service.
