A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Register (MSR) access with nested(=1) virtualization enabled. In that, L1 guest could access L0’s APIC register values via L2 guest, when ‘virtualize x2APIC mode’ is enabled. A guest could use this flaw to potentially crash the host kernel resulting in DoS issue.
