| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-02-13 | CVE-2023-20579 | Unspecified vulnerability in AMD products Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) privileged access to bypass protections potentially resulting in loss of integrity and availability. | 6.0 |
| 2024-01-16 | CVE-2023-4969 | Memory Leak vulnerability in multiple products A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called _local memory_ on various architectures. | 6.5 |
| 2023-11-14 | CVE-2021-46758 | Unspecified vulnerability in AMD products Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allow an attacker to read data in memory mapped beyond SPI flash resulting in a potential loss of availability and integrity. low complexity amd | 6.1 |
| 2023-03-01 | CVE-2022-27672 | Unspecified vulnerability in AMD products When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure. | 4.7 |
| 2022-11-09 | CVE-2022-23824 | IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. | 5.5 |
| 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 |
| 2022-07-14 | CVE-2022-23825 | Exposure of Resource to Wrong Sphere vulnerability in multiple products Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure. | 6.5 |
| 2022-07-12 | CVE-2022-29900 | Improper Cross-boundary Removal of Sensitive Data vulnerability in multiple products Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. | 6.5 |
| 2022-06-15 | CVE-2022-23823 | Information Exposure Through Discrepancy vulnerability in AMD products A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure. | 6.5 |
