low complexity
amd CWE-787
7.5
2023-05-09 CVE-2021-46764 Out-of-bounds Write vulnerability in AMD products
Improper validation of DRAM addresses in SMU may allow an attacker to overwrite sensitive memory locations within the ASP potentially resulting in a denial of service.
network
low complexity
amd CWE-787
7.5
2023-05-09 CVE-2021-46769 Improper Input Validation vulnerability in AMD products
Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to execute arbitrary DMA copies, which can lead to code execution.
network
low complexity
amd CWE-20
8.8
2023-05-09 CVE-2022-23818 Improper Input Validation vulnerability in AMD products
