The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - kernel/fail_function: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result     must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call     debugfs_lookup_and_remove() instead which handles all of the logic at once. (CVE-2023-53346)

Note that Nessus relies on the presence of the package as reported by the vendor.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992536 advisory.
