CVE-2021-26401

CVE-2021-26401 concerns Spectre Variant 2 mitigation on AMD CPUs. The description states that LFENCE/JMP mitigation (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD processors. AMD advisories (AMD-SB-1040 and AMD-SB-1036) discuss mitigations and supported approaches: use ...

CVE-2022-29900

CVE-2022-29900 describes mis-trained branch predictions for return instructions that may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. Connected advisories confirm this affects Linux-kernel components (e.g., linux-5.10 in Astra Linux; multiple Am...

CVE-2022-23825

CVE-2022-23825 affects AMD processors where branch-predictor aliases can cause misclassification of branches, potentially exposing information. The connected advisories show Linux kernel mitigations are being released for Amazon Linux 2/ALAS kernels (e.g., ALAS2KERNEL-5.10-2025-086 and ALAS2KERNE...

CVE-2021-26341

CVE-2021-26341 affects AMD CPUs; transient execution beyond unconditional direct branches may leak data. Public details describe local access risk with low NVD CVSS v2 but medium CVSS v3.1 (6.5) and local attack vector. Connected advisories (MiracleLinux, IBM/Red Hat and others) mention this CVE ...

CVE-2022-23824

Summary: CVE-2022-23824 is listed as a Xen-related vulnerability in Debian security advisories and Gentoo GLSA, indicating multiple vulnerabilities in the Xen hypervisor that could lead to privilege escalation, denial of service, or information leaks. The Debian entry explicitly groups CVE-2022-2...

CVE-2022-27672

CVE-2022-27672 describes a local information disclosure vulnerability on certain AMD CPUs where, when SMT is enabled, the processor may speculatively execute instructions using a target from the sibling thread after an SMT mode switch. The underlying issue is tied to speculative execution across ...

CVE-2022-23823

CVE-2022-23823 describes a timing-attack information disclosure risk on AMD processors with DVFS. Connected sources show F5 advisories (K43357358) tying Hertzbleed to BIG-IP on AMD CPUs, listing affected BIG-IP branches (e.g., 17.x up to 17.5.03) with “Will not fix” for some lines, and provide a ...
