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

  - mptcp: options: reset DSS fields in case of unexpected size A remote peer could send a malformed DSS with     a wrong size, followed by another DSS or MPC + Data. In this case, the first suboption will be ignored,     but leaving some fields written, which could lead to inconsistency or access uninitialized data.
    Explicitly reset the fields that could have been modified in case of unexpected size. (CVE-2026-80586)

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