Name of the Vulnerable Software and Affected Versions
AMD BIOS software (affected versions not specified)
Description
The issue is related to insufficient bounds checking in the AMD Secure Processor firmware when handling BIOS mailbox commands. This can allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions, potentially leading to a loss of integrity and availability of protected information.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
