CVE:

  • CVE-2023-20592
  • Severity: Medium

Affected products:

Supermicro BIOS in the H11 and H12 motherboards

Remediation:

Note (per AMD): No mitigation is available for the first or second generations of EPYC™ processors (“Zen 1”, formerly codenamed “Naples”, “Zen 2”, formerly codenamed “Rome”) since the SEV and SEV-ES features are not designed to protect guest VM memory integrity and the SEV-SNP is not available.
