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

  - A weakness has been identified in libimobiledevice up to 1.4.0. This issue affects the function
    service_receive of the file src/afc.c of the component AFC Service. Executing a manipulation can lead to
    double free. The attack may be performed from remote. The exploit has been made available to the public
    and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in
    any way. (CVE-2026-116260)

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