    Security Fix(es):

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page(s) listed in the References section.

    Additional Changes:

    For detailed information on changes in this release, see the Rocky Linux 8.10 Release Notes linked from
    the References section.

Tenable has extracted the preceding description block directly from the Rocky Linux security advisory.
