发布于3月6日3月6日 Members Ubuntu: (Multiple Advisories) (CVE-2023-1095): Linux kernel (AWS) vulnerabilities Severity 5 CVSS (AV:L/AC:L/Au:S/C:N/I:N/A:C) Published 02/28/2023 Created 05/05/2023 Added 04/10/2023 Modified 01/28/2025 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.
