Statement
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. In most cases, it 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-owned development processes and QA documentation) for releasing this content as RHSA. For more information, please contact the binary content vendor.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
