Description OSIDB Bzimport 2026-11-10 22:21:48 UTC 
Improper enforcement of behavioral workflow in AMD Secure Encrypted Virtualization (SEV) firmware could allow a malicious hypervisor to potentially launch a guest whose attestation report contains an ID key digest for an ID block that doesn't match the guest's measurement resulting in loss of integrity.
