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

  - tcp: Fix potential UAF in reqsk_timer_handler(). When TCP socket migration fails at inet_ehash_insert() in     reqsk_timer_handler(), we jump to the no_ownership: label and free the new reqsk immediately with
    __reqsk_free(). Thus, we must stop the new reqsk's timer before jumping to the label, but the timer might     be missed since the cited commit, resulting in UAF. As we are in the original reqsk's timer context, we     can safely call timer_delete_sync() for the new reqsk. Let's pass false to __inet_csk_reqsk_queue_drop()     to stop the new reqsk's timer. (CVE-2026-99270)

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