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

  - A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs
    introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This
    corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue
    could allow clients connecting to the read-only socket to crash the virtinterfaced daemon. (CVE-2024-8235)

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