DATE CVE VULNERABILITY TITLE RISK
2024-08-13 CVE-2023-20578 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary code execution.

high complexity
amd CWE-367
6.4
2024-02-13 CVE-2023-31346 Unspecified vulnerability in AMD products
Failure to initialize memory in SEV Firmware may allow a privileged attacker to access stale data from other guests.

6.0
2024-02-13 CVE-2023-31347 Unspecified vulnerability in AMD products
Due to a code bug in Secure_TSC, SEV firmware may allow an attacker with high privileges to cause a guest to observe an incorrect TSC when Secure TSC is enabled potentially resulting in a loss of guest integrity.

4.9
2024-01-11 CVE-2023-20573 Unspecified vulnerability in AMD products
A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information.

3.2
2023-11-14 CVE-2021-26345 Out-of-bounds Read vulnerability in AMD products
Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service.

low complexity
amd CWE-125
4.9
2023-11-14 CVE-2021-46774 Unspecified vulnerability in AMD products
Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service.

5.3
2023-11-14 CVE-2023-20521 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products
TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service.
high complexity
amd CWE-367
5.7
2023-11-14 CVE-2023-20526 Unspecified vulnerability in AMD products
Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality.
low complexity
