| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2022-05-11 | CVE-2021-26347 | Improper Validation of Specified Quantity in Input vulnerability in AMD products Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service. | 4.7 |
| 2022-05-11 | CVE-2021-26350 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products A TOCTOU race condition in SMU may allow for the caller to obtain and manipulate the address of a message port register which may result in a potential denial of service. | 4.7 |
| 2022-05-11 | CVE-2021-26364 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bounds checking in an SMU mailbox register could allow an attacker to potentially read outside of the SRAM address range which could result in an exception handling leading to a potential denial of service. | 5.5 |
| 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. | 5.5 |
| 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. | 5.5 |
| 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. | 5.5 |
| 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 |
