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

  - net/sched: cls_api: Handle TC_ACT_CONSUMED in tcf_qevent_handle tcf_classify() can return TC_ACT_CONSUMED     while the skb is held by the defragmentation engine (e.g. act_ct on out-of-order fragments). When that     happens the skb is no longer owned by the caller and must not be touched again. tcf_qevent_handle() did     not handle TC_ACT_CONSUMED: it fell through the switch and returned the skb to the caller as if     classification had passed. The only qdisc that wires up qevents today is RED, via three call sites     (qe_mark on RED_PROB_MARK/HARD_MARK, qe_early_drop on congestion_drop) red_enqueue() was continuing to     operate on an skb it no longer owns in this case -- enqueueing it, dropping it, or updating statistics.
    Resulting in a UAF. tc qdisc add dev eth0 root handle 1: red ... qevent early_drop block 10 tc filter add     block 10 ... action ct (with ct defrag enabled and traffic that produces out-of-order fragments, e.g. a     fragmented UDP stream) Handle TC_ACT_CONSUMED in tcf_qevent_handle() the same way the ingress and egress     fast paths do: treat it as stolen and return NULL without touching the skb. Unlike the TC_ACT_STOLEN case,     the skb must not be dropped/freed here, as it is no longer owned by us. (CVE-2026-64530)

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