https://notcve.org/view.php?id=CVE-2021-26401
LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs. LFENCE/JMP (mitigación V2-2) puede no mitigar suficientemente CVE-2017-5715 en algunas CPUs AMD A flaw was found in hw. The speculative execution window of AMD LFENCE/JMP mitigation (MITIGATION V2-2) may be large enough to be exploited on AMD CPUs. • http://www.openwall.com/lists/oss-security/2022/03/18/2 https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1036 https://access.redhat.com/security/cve/CVE-2021-26401 https://bugzilla.redhat.com/show_bug.cgi?id=2061700 •
