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

  - netfilter: nf_tables: always walk all pending catchall elements During transaction processing we might     have more than one catchall element: 1 live catchall element and 1 pending element that is coming as part     of the new batch. If the map holding the catchall elements is also going away, its required to toggle all     catchall elements and not just the first viable candidate. Otherwise, we get: WARNING:
    ./include/net/netfilter/nf_tables.h:1281 at nft_data_release+0xb7/0xe0 [nf_tables], CPU#2: nft/1404 RIP:
