Florian Westphal 8a2df34b5b netfilter: nf_tables: fix null deref due to zeroed list head ... commit 580077855a upstream. In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a null dereference: BUG: KASAN: null-ptr-deref in nft_trans_destroy+0x26/0x59 Call Trace: nft_trans_destroy+0x26/0x59 nf_tables_newtable+0x4bc/0x9bc [..] Its sane to assume that nft_trans_destroy() can be called on the transaction object returned by nft_trans_alloc(), so make sure the list head is initialised.
