low complexity
amd CWE-125
5.5
2023-01-11 CVE-2021-46791 Out-of-bounds Write vulnerability in AMD Milanpi Firmware
Insufficient input validation during parsing of the System Management Mode (SMM) binary may allow a maliciously crafted SMM executable binary to corrupt Dynamic Root of Trust for Measurement (DRTM) user application memory that may result in a potential denial of service.
local
low complexity
amd CWE-787
5.5
2023-01-11 CVE-2021-46795 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
A TOCTOU (time-of-check to time-of-use) vulnerability exists where an attacker may use a compromised BIOS to cause the TEE OS to read memory out of bounds that could potentially result in a denial of service.
local
high complexity
amd CWE-367
4.7
2023-01-11 CVE-2022-23813 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD Milanpi-Sp3 Firmware and Romepi Firmware
