CVE-2026-64308

A flaw was found in the Linux kernel's crypto: ccp module, which handles AMD Secure Encrypted Virtualization SEV and Secure Nested Paging SNP features. A local user, by sending specific commands through the /dev/sev interface, could exploit improper initialization handling. If SEV initialization...

CVE-2026-64309

A flaw was found in the Linux kernel's crypto: ccp module. This vulnerability arises from improper initialization of Secure Nested Paging SNP when handling the ioctlSNPCOMMIT command. A local userspace process can exploit this by sending specific commands via /dev/sev ioctls. If Secure Encrypted...
