Amd Processors vulnerabilities

CVE-2022-23824 [MEDIUM] CVE-2022-23824: IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leadi IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure.

CVE-2021-46778 [MEDIUM] CWE-203 CVE-2021-46778: Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microa 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). By measuring the contention level on scheduler queues an attacker may potentially leak sensitive information.

CVE-2022-23825 [MEDIUM] CWE-668 CVE-2022-23825: Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type poten Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.

CVE-2022-29900 [MEDIUM] CWE-212 CVE-2022-29900: Mis-trained branch predictions for return instructions may allow arbitrary speculative code executio Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.

CVE-2022-23823 [MEDIUM] CWE-203 CVE-2022-23823: A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated 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.

CVE-2021-46744 [MEDIUM] CWE-203 CVE-2021-46744: An attacker with access to a malicious hypervisor may be able to infer data values used in a SEV gue 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.

CVE-2021-26400 [MEDIUM] CVE-2021-26400: AMD processors may speculatively re-order load instructions which can result in stale data being obs AMD processors may speculatively re-order load instructions which can result in stale data being observed when multiple processors are operating on shared memory, resulting in potential data leakage.
