| 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. | 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. | 4.9 |
| 2023-11-14 | CVE-2021-46766 | Incomplete Cleanup vulnerability in AMD products Improper clearing of sensitive data in the ASP Bootloader may expose secret keys to a privileged attacker accessing ASP SRAM, potentially leading to a loss of confidentiality. | 5.5 |
| 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. | 7.5 |
| 2023-11-14 | CVE-2022-23830 | Unspecified vulnerability in AMD products SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity. | 5.3 |
| 2023-11-14 | CVE-2023-20566 | Unspecified vulnerability in AMD products Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity. | 7.5 |
| 2023-08-08 | CVE-2023-20569 | Information Exposure Through Discrepancy vulnerability in multiple products A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. | 4.7 |
