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

  - undici's experimental WebSocketStream client crashes the whole Node.js process when a remote peer closes
    the TCP connection without a WebSocket close handshake. On an unclean close the internal socket-close
    handler calls abort on the writable stream unconditionally and discards the returned promise, but per the
    WHATWG Streams standard aborting a locked writable returns a promise that rejects with a TypeError.
    Because the application holds a writer on that writable, which is the only way to write, the rejection is
    never observed and Node's default unhandled-rejection behavior terminates the process. An untrusted server
    can therefore crash a client with a single abrupt disconnect, with no authentication and no application
    mistake. This affects undici versions from 7.0.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should
    upgrade to undici 7.29.1 or 8.10.2. (CVE-2026-85014)

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