"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: ccp - Do not initialize SNP for ioctl(SNP_COMMIT)\n\nSashiko notes:\n\n> if SEV initialization fails and KVM is actively running normal VMs, could a\n> userspace process trigger this code path via /dev/sev ioctls (e.g.,\n> SEV_PDH_GEN) and zero out MSR_VM_HSAVE_PA globally? Would the next VMRUN\n> execution for an active VM trigger a general protection fault and crash the\n> host?\n\nThe SNP_COMMIT command does not require the firmware to be in any\nparticular state. Skip initializing it if it was previously uninitialized.\n\nThe SEV-SNP firmware specification doc 56860 does not mention SNP_COMMIT in\nTable 5 as a command that is allowed in the UNINIT state, but it is in fact\nallowed and a future documentation update will reflect that."
