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...

CVE-2022-50226
CVE-2022-50226 affects the Linux kernel crypto: ccp subsystem, where sev ioctl interfaces could allocate memory with kmalloc to handle input up to SEV_FW_BLOB_MAX_SIZE but were not fully overwritten by PSP firmware, risking uninitialized slab memory. The issue is resolved by changing ioctl memory...
