| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2022-05-11 | CVE-2021-46744 | Information Exposure Through Discrepancy vulnerability in AMD products An attacker with access to a malicious hypervisor may be able to infer data values used in a SEV guest on AMD CPUs by monitoring ciphertext values over time. | 6.5 |
| 2022-03-11 | CVE-2021-26341 | Improper Cross-boundary Removal of Sensitive Data vulnerability in AMD products Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage. | 6.5 |
| 2022-03-11 | CVE-2021-26401 | Unspecified vulnerability in AMD products LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs. | 5.6 |
| 2022-02-04 | CVE-2020-12966 | Information Exposure vulnerability in AMD products AMD EPYC™ Processors contain an information disclosure vulnerability in the Secure Encrypted Virtualization with Encrypted State (SEV-ES) and Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP). | 5.5 |
| 2021-12-10 | CVE-2021-26340 | Unspecified vulnerability in AMD products A malicious hypervisor in conjunction with an unprivileged attacker process inside an SEV/SEV-ES guest VM may fail to flush the Translation Lookaside Buffer (TLB) resulting in unexpected behavior inside the virtual machine (VM). | 8.4 |
| 2021-11-16 | CVE-2020-12944 | Improper Input Validation vulnerability in AMD products Insufficient validation of BIOS image length by ASP Firmware could lead to arbitrary code execution. | 7.8 |
| 2021-11-16 | CVE-2021-26320 | Improper Certificate Validation vulnerability in AMD products Insufficient validation of the AMD SEV Signing Key (ASK) in the SEND_START command in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP | 5.5 |
| 2021-11-16 | CVE-2021-26321 | Command Injection vulnerability in AMD products Insufficient ID command validation in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP. | 5.5 |
| 2021-11-16 | CVE-2021-26312 | Exposure of Resource to Wrong Sphere vulnerability in AMD products Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity. | 5.5 |
| 2021-11-16 | CVE-2021-26322 | Use of Insufficiently Random Values vulnerability in AMD products Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”. | 7.5 |
