DATE CVE VULNERABILITY TITLE RISK
2024-08-13 CVE-2021-26344 Out-of-bounds Write vulnerability in AMD products
An out of bounds memory write when processing the AMD PSP1 Configuration Block (APCB) could allow an attacker with access the ability to modify the BIOS image, and the ability to sign the resulting image, to potentially modify the APCB block resulting in arbitrary code execution.
