**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 4.2.7 Xen versions 4.3.x through 4.6.x **Description** The issue is related to errors in resource management within the KVM subsystem of the Linux kernel and the Xen hypervisor. It allows a local attacker to cause a denial of service by triggering many Alignment Check exceptions, which can lead to a host OS panic or hang. This is related to the svm.c and vmx.c files. **Recommendations** For Linux kernel versions prior to 4.2.7, update to version 4.2.7 or later to resolve the issue. For Xen versions 4.3.x through 4.6.x, consider disabling the KVM subsystem temporarily until a patch is available. Restrict access to the svm.c and vmx.c components to minimize the risk of exploitation.
