low complexity
amd CWE-295
5.5
2021-11-16 CVE-2021-26321 Command Injection vulnerability in AMD products
Insufficient ID command validation in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP.
local
low complexity
amd CWE-77
5.5
2021-11-16 CVE-2021-26330 Out-of-bounds Write vulnerability in AMD products
AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources.
