| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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 |
| 2022-05-11 | CVE-2021-26342 | Unspecified vulnerability in AMD products In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). | 3.3 |
| 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-2021-26408 | 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. | 7.1 |
| 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 |
