The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 55c4e822-b4e4-11f0-8438-001b217e4ee5 advisory.

    Internet Systems Consortium, Inc. reports:
    To trigger the issue, three configuration parameters            must have specific settings: hostname-char-set must be            left at the default setting, which is [^A-Za-z0-9.-];
           hostname-char-replacement must be empty (the default);
           and ddns-qualifying-suffix must NOT be empty (the default is empty).
           DDNS updates do not need to be enabled for this issue to manifest.
           A client that sends certain option content would then            cause kea-dhcp4 to exit unexpectedly.
           This addresses CVE-2025-11232 [#4142, #4155].

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

  - To trigger the issue, three configuration parameters must have specific settings: hostname-char-set must     be left at the default setting, which is [^A-Za-z0-9.-]; hostname-char-replacement must be empty (the     default); and ddns-qualifying-suffix must *NOT* be empty (the default is empty). DDNS updates do not     need to be enabled for this issue to manifest. A client that sends certain option content would then cause     kea-dhcp4 to exit unexpectedly. This issue affects Kea versions 3.0.1 through 3.0.1 and 3.1.1 through     3.1.2. (CVE-2025-11232)

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