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

  - net/sched: accept TCA_STAB only for root qdisc Most qdiscs maintain their backlog using qdisc_pkt_len(skb)     on the assumption it is invariant between the enqueue() and dequeue() handlers. Unfortunately syzbot can     crash a host rather easily using a TBF + SFQ combination, with an STAB on SFQ [1] We can't support     TCA_STAB on arbitrary level, this would require to maintain per-qdisc storage.
