"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nfnetlink_queue: fix entry leak in bridge verdict error path\n\nnfqnl_recv_verdict() calls find_dequeue_entry() to remove the queue\nentry from the queue data structures, taking ownership of the entry.\nFor PF_BRIDGE packets, it then calls nfqa_parse_bridge() to parse VLAN\nattributes. If nfqa_parse_bridge() returns an error (e.g. NFQA_VLAN\npresent but NFQA_VLAN_TCI missing), the function returns immediately\nwithout freeing the dequeued entry or its sk_buff.\n\nThis leaks the nf_queue_entry, its associated sk_buff, and all held\nreferences (net_device refcounts, struct net refcount). Repeated\ntriggering exhausts kernel memory.\n\nFix this by dropping the entry via nfqnl_reinject() with NF_DROP verdict\non the error path, consistent with other error handling in this file."
