Severity
6.7 (Medium) - cvssV3_0 - CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:H
Summary
A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (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. Kernel versions from 4.16 and newer are vulnerable to this issue.
