It has been classified as problematic. This affects an unknown part of the component System Management Mode. The manipulation with an unknown input leads to a improper access control for volatile memory containing boot code vulnerability. CWE is classifying the issue as CWE-1274. The product conducts a secure-boot process that transfers bootloader code from Non-Volatile Memory (NVM) into Volatile Memory (VM), but it does not have sufficient access control or other protections for the Volatile Memory. This is going to have an impact on confidentiality. The summary by CVE is:

Improper input validation in the AMD OverDrive (AOD) System Management Mode (SMM) module could allow a privileged attacker to perform an out-of-bounds read, potentially resulting in loss of confidentiality.

The advisory is shared at amd.com. This vulnerability is uniquely identified as CVE-2024-36345 since 05/23/2024. The exploitability is told to be easy. An attack has to be approached locally. The exploitation needs additional levels of successful authentication. Neither technical details nor an exploit are publicly available.
