| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2022-05-11 | CVE-2021-26372 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bound checks related to PCIE in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service. | 4.9 |
| 2022-05-11 | CVE-2021-26373 | Improper Input Validation vulnerability in AMD products Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunction that could result in denial of resources and/or possibly denial of service. | 5.5 |
| 2022-05-11 | CVE-2021-26375 | Unspecified vulnerability in AMD products Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in access/updates from/to invalid address space that could result in denial of service. | 4.9 |
| 2022-05-11 | CVE-2021-26376 | Unspecified vulnerability in AMD products Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service. | 5.5 |
| 2022-05-11 | CVE-2021-26378 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service. | 4.9 |
| 2022-05-11 | CVE-2021-26388 | Out-of-bounds Read vulnerability in AMD products Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service. | 5.5 |
| 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 |
| 2022-05-10 | CVE-2021-26370 | Improper Input Validation vulnerability in AMD products Improper validation of destination address in SVC_LOAD_FW_IMAGE_BY_INSTANCE and SVC_LOAD_BINARY_BY_ATTRIB in a malicious UApp or ABL may allow an attacker to overwrite arbitrary bootloader memory with SPI ROM contents resulting in a loss of integrity and availability. | 6.6 |
| 2022-05-10 | CVE-2021-26408 | Unspecified vulnerability in AMD products Insufficient validation of elliptic curve points in SEV-legacy firmware may compromise SEV-legacy guest migration potentially resulting in loss of guest's integrity or confidentiality. | 6.6 |
| 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 |
