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

  - netfilter: nft_counter: serialize reset with spinlock Add a global static spinlock to serialize counter     fetch+reset operations, preventing concurrent dump-and-reset from underrunning values. The lock is taken     before fetching the total so that two parallel resets cannot both read the same counter values and then     both subtract them. A global lock is used for simplicity since resets are infrequent. If this becomes a     bottleneck, it can be replaced with a per-net lock later. (CVE-2026-45897)

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