CVE-2023-1095 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
