CVE-2025-38455

CVE-2025-38455 is a Linux kernel/KVM vulnerability in the KVM: SVM path. The issue occurs during SEV{-ES} intra-host migration when a vCPU is being created (in-flight) on either source or destination VM, where SEV{-ES} state can be toggled to non-SEV{-ES} in the destination. This can lead to a cr...
