Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.5.0-smp--fff2e47e6c3b-next #151

Description The Linux kernel contains a flaw within the KVM component related to SEV-ES intrahost migration. A mistake in the code causes KVM to attempt to retrieve source vCPUs from the destination VM instead of the source VM during migration. This can lead to guest corruption and a host crash due to a NULL VMSA pointer. The issue manifests as a page fault error during memory access.

Recommendations Update to Linux kernel version 6.5.0-smp--fff2e47e6c3b-next #151 or a later version to address this issue.
