| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-01-11 | CVE-2023-20528 | Improper Input Validation vulnerability in AMD products Insufficient input validation in the SMU may allow a physical attacker to exfiltrate SMU memory contents over the I2C bus potentially leading to a loss of confidentiality. | 2.4 |
| 2023-01-11 | CVE-2023-20529 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bound checks in the SMU may allow an attacker to update the from/to address space to an invalid value potentially resulting in a denial of service. | 7.5 |
| 2023-01-11 | CVE-2023-20531 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bound checks in the SMU may allow an attacker to update the SRAM from/to address space to an invalid value potentially resulting in a denial of service. | 7.5 |
| 2023-01-11 | CVE-2023-20532 | Improper Input Validation vulnerability in AMD products Insufficient input validation in the SMU may allow an attacker to improperly lock resources, potentially resulting in a denial of service. | 5.3 |
| 2022-08-10 | CVE-2021-46778 | Information Exposure Through Discrepancy vulnerability in AMD products Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). | 5.6 |
| 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 |
