Vulnerability Title
KVM: SVM: Get source vCPUs from source VM for SEV-ES intrahost migration
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Get source vCPUs from source VM for SEV-ES intrahost migration Fix a goof where KVM tries to grab source vCPUs from the destination VM when doing intrahost migration. Grabbing the wrong vCPU not only hoses the guest, it also crashes the host due to the VMSA pointer being left NULL.
