In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
KVM: SEV: Do not allow intra-host migration\/mirroring of SNP VMs<\/p>\n
The intra-host migration\/mirroring feature is not fully implemented for
\nSEV-SNP VMs. The proper migration requires additional SNP-specific
\nstate such as guest_req_mutex, guest_req_buf, and guest_resp_buf to be
\ntransferred or initialized on the destination.<\/p>\n
The SNP VM mirroring requires vmsa features to be copied as well otherwise
\nASID would be bound to SNP range while VM is detected as a SEV VM.<\/p>\n
Reject SNP source VMs in migration\/mirroring until proper SNP state
\ntransfer is implemented.<\/p>\n
