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

  - A vulnerability was detected in Kamailio up to 6.0.7/6.1.3. The affected element is the function
    isup_get_calling_party of the file src/modules/sipt/ss7_parser.c of the component sipt Module. The
    manipulation of the argument length results in buffer overflow. The attack may be performed from remote.
    Upgrading to version 6.0.8 and 6.1.4 is sufficient to fix this issue. The patch is identified as
    3667bebf8d0bea07ed16218fd921d07db87aeb21. Upgrading the affected component is advised. (CVE-2026-108822)

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