  "description": "In the Linux kernel, the following vulnerability has been resolved:  udp: call skb_orphan() before skb_attempt_defer_free()  Standard UDP receive path does not use skb-\u003Edestructor.  But skmsg layer does use it, since it calls skb_set_owner_sk_safe() from udp_read_skb().  This then triggers this warning in skb_attempt_defer_free():      DEBUG_NET_WARN_ON_ONCE(skb-\u003Edestructor);  We must call skb_orphan() to fix this issue.",
