| Vulnerability Name: | CVE-2023-1095 (CCN-249041) |
| Assigned: | 2022-08-09 |
| Published: | 2022-08-09 |
| Updated: | 2023-03-06 |
| 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. |
