| 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 |
| 2024-08-13 | CVE-2023-20584 | Unspecified vulnerability in AMD products IOMMU improperly handles certain special address ranges with invalid device table entries (DTEs), which may allow an attacker with privileges and a compromised Hypervisor to induce DTE faults to bypass RMP checks in SEV-SNP, potentially leading to a loss of guest integrity. | 6.0 |
| 2024-08-05 | CVE-2023-31355 | Out-of-bounds Write vulnerability in AMD products Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to overwrite a guest's UMC seed potentially allowing reading of memory from a decommissioned guest. | 6.0 |
| 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 |
| 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-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-2023-20521 | 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. | 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 amd | 4.6 |
| 2023-11-14 | CVE-2023-20592 | Unspecified vulnerability in AMD products Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) memory integrity. | 6.5 |
