CVE-2023-1095 is a NULL pointer dereference in the Linux kernel Netfilter nf_tables table-update path. If nf_tables_updtable() encounters an error from nf_tables_table_enable(), it invokes nft_trans_destroy() on a transaction object that was never linked into its expected list. nft_trans_destroy() subsequently calls list_del() against the zero-initialized list head, resulting in a NULL pointer dereference.
