CVE-2023-1095

Summary

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 pointer dereference.
