CVE-2025-48514
Insufficient Granularity of Access Control in SEV firmware can allow a privileged attacker to create a SEV-ES Guest to attack SNP guest, potentially resulting in a loss of confidentiality.
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
