| Mauro Matteo Cascella | 2023-04-27 17:49:48 UTC | Doc Text | A flaw was found in the KVM's Intel nested virtualization feature (nVMX). The effective values of the guest CR0 and CR4 registers could differ from those included in the VMCS12. This could allow a malicious nested guest to cause a denial of service condition or other undefined behaviors. | |

The effective values of the guest CR0 and CR4 registers could differ from those included in the VMCS12. In rare circumstances (i.e., kvm_intel module loaded with parameters nested=1 and ept=0) this could allow a malicious guest to crash the host system, causing a denial of service. |
