AMD AMD Processors

• CVE-2022-23824 Unrated IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. 0.6%
• CVE-2021-46778 Unrated 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 m 0.2%
• CVE-2022-23825 Unrated Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure. 0.8%
• CVE-2022-29900 Unrated Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. 3.9%
• CVE-2022-23823 Unrated 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. 1.2%
• CVE-2021-46744 Unrated 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. 0.3%
• CVE-2021-26400 Unrated 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. 0.2%
• CVE-2021-26341 Unrated Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage. 0.3%
• CVE-2021-26401 Unrated LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs. 0.3%
• CVE-2020-12890 Unrated Improper handling of pointers in the System Management Mode (SMM) handling code may allow for a privileged attacker with physical or administrative access to potentially manipulate the AMD Generic Enc 0.3%
