CVE-2026-64308

CVE-2026-64308 affects the Linux kernel's crypto:ccp module, which handles AMD SEV (Secure Encrypted Virtualization) and SNP (Secure Nested Paging). The root cause is that the ioctl(SNP_VLEK_LOAD) handler performed a pointless init/shutdown wrapper—firmware deletes the VLEK on SNP_SHUTDOWN anyway...
