CVE-2024-0179

Red Hat statement

These vulnerabilities can allow a ring 0 attacker to escalate their privileges, potentially resulting in arbitrary code execution within SMM. Red Hat has very limited to no visibility and control over binary blobs provided by third-party vendors. Red Hat relies heavily on the vendors to provide timely updates and information about included changes for this content and in most cases merely acts as a release vehicle between the third-party vendor and Red Hat customers with no possibility of influencing or even documenting the changes. Unless explicitly stated, the level of insight, oversight, and control Red Hat has does not meet the criteria required (in terms of Red Hat ownership of development processes, QA, and documentation) for releasing this content as RHSA. For more information please contact the binary content vendor.

Red Hat mitigation

Available mitigation requires updating the BIOS (updating firmware of the CPU). The bug affects hardware (processors of the AMD EPYC™ family).
