"The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the
ELSA-2023-6409 advisory.

  - A flaw was found in libvirt. The virStoragePoolObjListSearch function does not return a locked pool as
    expected, resulting in a race condition and denial of service when attempting to lock the same object from
    another thread. This issue could allow clients connecting to the read-only socket to crash the libvirt
    daemon. (CVE-2023-3750)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
