Supermicro is aware of the AMD INVD Instruction security vulnerability. This issue affects 1st Gen AMD EPYC™ Processors (SEV and SEV-ES), 2nd Gen AMD EPYC™ Processors (SEV and SEV-ES), and 3rd Gen AMD EPYC™ Processors (SEV, SEV-ES, SEV-SNP).
- Severity: Medium
Supermicro BIOS in the H11 and H12 motherboards
Supermicro is currently working on updating BIOS to mitigate this issue. This page will be updated as additional information becomes available.
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.
