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

  - net/sched: fix pedit partial COW leading to page cache corruption tcf_pedit_act() computes the COW range     for skb_ensure_writable() once before the key loop using tcfp_off_max_hint, but the hint does not account     for the runtime header offset added by typed keys. This can leave part of the write region un-COW'd. Fix     by moving skb_ensure_writable() inside the per-key loop where the actual write offset is known, and add     overflow checking on the offset arithmetic. For negative offsets (e.g. Ethernet header edits at ingress),     use skb_cow() to COW the headroom instead. Guard offset_valid() against INT_MIN, where negation is     undefined. (CVE-2026-46331)

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