AMD Release Firmware Patch for SEV
AMD have released firmware patch for the Secure Encrypted Virtualisation (SEV) which provides hardware accelerated memory encryption for data-in-user protection.
AMD, partnering with industry researchers, discovered encryption keys could be compromised by manipulating the encryption technology’s behaviour.
Attackers must have local access to the management interfaces of SEV with sufficient privileges, although that may or may not be admin privileges, depending on how SEV is being used.
Ensure that firmware patches have been applied to your Epyc AMD chips.
