**Name of the Vulnerable Software and Affected Versions** Linux Kernel versions 4.16 and newer **Description** The issue is related to a flaw in the KVM hypervisor's handling of x2APIC Machine Specific Register (MSR) access with nested virtualization enabled, allowing a guest to potentially access the host's APIC register values and crash the host kernel, resulting in a denial of service. **Recommendations** For Linux Kernel versions 4.16 and newer, update to a version that includes a fix for this issue to prevent potential denial of service attacks.
