Calling skb_dst_set_noref() when skb already holds a ref-counted dst overwrites skb-\u003e_skb_refdst, leaking the previous dst_entry reference count and triggering a DEBUG_NET_WARN_ON_ONCE assertion in skb_dst_check_unset():    WARNING: at skb_dst_check_unset include/linux/skbuff.h:1170   WARNING: at skb_dst_set_noref include/linux/skbuff.h:1234   WARNING: at nf_flow_offload_ip_hook+0xf6c/0x2b60 net/netfilter/nf_flow_table_ip.c:864  Drop any existing dst_entry reference with skb_dst_drop(skb) before setting the non-referenced flowtable destination.",
