CWE-476

Description

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.

Affected configurations

• linux linux kernel (< 6.0) • redhat enterprise linux 8.0 • redhat enterprise linux 9.0
