      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_queue: hold bridge skb->dev while queued\n\nbr_pass_frame_up() rewrites skb->dev from the ingress port to the bridge\nmaster before queueing bridge LOCAL_IN packets. NFQUEUE only holds\nreferences on state.in/out and bridge physdevs, so a queued bridge\npacket can retain a freed bridge master in skb->dev until reinjection.\n\nWhen the verdict is reinjected later, br_netif_receive_skb() re-enters\nthe receive path with skb->dev still pointing at the freed bridge master,\ntriggering a use-after-free.\n\nStore skb->dev in the queue entry, hold a reference on it for the queue\nlifetime, and use the saved device when dropping queued packets during\nNETDEV_DOWN handling.",
