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: unconditionally bump set->nelems before insertion In case that the set is full, a     new element gets published then removed without waiting for the RCU grace period, while RCU reader can be     walking over it already. To address this issue, add the element transaction even if set is full, but     toggle the set_full flag to report -ENFILE so the abort path safely unwinds the set to its previous state.
    As for element updates, decrement set->nelems to restore it. A simpler fix is to call synchronize_rcu() in     the error path. However, with a large batch adding elements to already maxed-out set, this could cause     noticeable slowdown of such batches. (CVE-2026-23272)

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