Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the KVM SEV implementation where intra-host migration and mirroring are not fully supported for SEV-SNP VMs. Proper migration of these VMs requires the transfer or initialization of specific SNP states, including
guest req mutex, guest req buf, and guest resp buf, on the destination host. Additionally, SNP VM mirroring requires the copying of vmsa features; failure to do so may result in the ASID being bound to the SNP range while the VM is incorrectly detected as a SEV VM.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
