DATE CVE VULNERABILITY TITLE RISK
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-2021-46775 Improper Input Validation vulnerability in AMD products
Improper input validation in ABL may enable an attacker with physical access, to perform arbitrary memory overwrites, potentially leading to a loss of integrity and code execution.
low complexity
amd CWE-20
6.8
2023-05-09 CVE-2022-23818 Improper Input Validation vulnerability in AMD products
Insufficient input validation on the model specific register: VM_HSAVE_PA may potentially lead to loss of SEV-SNP guest memory integrity.

amd CWE-787
critical
9.8
2023-05-09 CVE-2023-20524 Out-of-bounds Write vulnerability in AMD products
An attacker with a compromised ASP could possibly send malformed commands to an ASP on another CPU, resulting in an out of bounds write, potentially leading to a loss a loss of integrity.
network
low complexity
amd CWE-787
7.5
2023-01-11 CVE-2021-26316 Improper Input Validation vulnerability in AMD products
Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.

2023-01-11 CVE-2021-26343 Exposure of Resource to Wrong Sphere vulnerability in AMD products
Insufficient validation in ASP BIOS and DRTM commands may allow malicious supervisor x86 software to disclose the contents of sensitive memory which may result in information disclosure.
local
low complexity
amd CWE-668
5.5
2023-01-11 CVE-2021-26355 Unspecified vulnerability in AMD products
Insufficient fencing and checks in System Management Unit (SMU) may result in access to invalid message port registers that could result in a potential denial-of-service.
