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

  - net: flow_dissector: use DEBUG_NET_WARN_ON_ONCE The following splat is easy to reproduce upstream as well     as in -stable kernels. Florian Westphal provided the following commit: d1dab4f71d37 (net: add and use
    __skb_get_hash_symmetric_net) but this complementary fix has been also suggested by Willem de Bruijn and     it can be easily backported to -stable kernel which consists in using DEBUG_NET_WARN_ON_ONCE instead to     silence the following splat given __skb_get_hash() is used by the nftables tracing infrastructure to to     identify packets in traces.
