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

  - bpf: Reject redirect helpers without a bpf_net_context The bpf_redirect*() helpers and skb_do_redirect()     obtain the per-task bpf_redirect_info via bpf_net_ctx_get_ri(), which dereferences the     current->bpf_net_context unconditionally. That context is established on the paths that run tc BPF such as     sch_handle_{ingress,egress}(), *except* for the case where {cls,act}_bpf was attached to a proper qdisc. A     program running from there reaches the NULL deref in two ways: * It calls bpf_redirect() directly, which     dereferences the context at the top of the helper: tc qdisc add dev eth0 root handle 1: red limit 1MB min     10KB max 20KB \ avpkt 1000 burst 100 qevent early_drop block 10 tc filter add block 10 pref 1 bpf obj     redirect.o * It simply returns TC_ACT_REDIRECT without helper call: tcf_qevent_handle() then dispatches to     skb_do_redirect(), which dereferences the context Rather than extending bpf_net_context management into     the qdisc path, make the redirect helpers refuse to operate when no context exists, and have     tcf_qevent_handle() drop a TC_ACT_REDIRECT verdict instead of calling skb_do_redirect(). Previous     behaviour was a crash, so nothing regresses by not supporting it. (CVE-2026-68337)

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