"The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2026:79101 advisory.

    Red Hat Ceph Storage is a scalable, open, software-defined storage platform that combines the most stable
    version of the Ceph storage system with a Ceph management platform, deployment utilities, and support
    services.

    These new packages include numerous security and bug fixes. Space precludes documenting all of these
    changes in this advisory. Users are directed to the Red Hat Ceph Storage Release Notes for information on
    the most significant of these changes:

    https://docs.redhat.com/en/documentation/red_hat_ceph_storage/8/html/8.1_release_notes

    ==========================================
    IMPORTANT:
    The Red Hat Ceph Storage team has migrated our defect tracking from Bugzilla to an internal Jira system.
    Bug fixes and CVE information that was previously listed in the errata releases are now listed in the
    Release Notes.

    Refer to the release notes going forward for the latest and most accurate fix and CVE information.
    ==========================================

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
