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: add hook transactions for device deletions Restore the flag that indicates that the     hook is going away, ie. NFT_HOOK_REMOVE, but add a new transaction object to track deletion of hooks     without altering the basechain/flowtable hook_list during the preparation phase. The existing approach     that moves the hook from the basechain/flowtable hook_list to transaction hook_list breaks netlink dump     path readers of this RCU-protected list. It should be possible use an array for nft_trans_hook to store     the deleted hooks to compact the representation but I am not expecting many hook object, specially now     that wildcard support for devices is in place. Note that the nft_trans_chain_hooks() list contains a list     of struct nft_trans_hook objects for DELCHAIN and DELFLOWTABLE commands, while this list stores struct     nft_hook objects for NEWCHAIN and NEWFLOWTABLE. Note that new commands can be updated to use     nft_trans_hook for consistency. This patch also adapts the event notification path to deal with the list     of hook transactions. (CVE-2026-63858)

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