low complexity
amd CWE-203
6.5
2023-05-09 CVE-2021-26354 Classic Buffer Overflow vulnerability in AMD products
Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised ABL which may cause arbitrary memory values to be initialized to zero, potentially leading to a loss of integrity.
local
low complexity
amd CWE-120
5.5
2023-05-09 CVE-2021-26371 Unspecified vulnerability in AMD products
A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may result in exposure of ASP memory to userspace, potentially leading to information disclosure.
