nft_ct: drop pending enqueued packets on removal","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nft_ct: drop pending enqueued packets on removal\n\nPackets sitting in nfqueue might hold a reference to:\n\n- templates that specify the conntrack zone, because a percpu area is\n  used and module removal is possible.\n- conntrack timeout policies and helper, where object removal leave\n  a stale reference.\n\nSince these objects can just go away, drop enqueued packets to avoid\nstale reference to them.\n\nIf there is a need for finer grain removal, this logic can be revisited\nto make selective packet drop upon dependencies.","state":0,"publishedAt":"2026-05-05T15:17:26.393+00:00","modifiedAt":"2026-10-19T19:06:11.915+00:00","affected":[{"ecosystem":"Vendor
