Medium [CVE-2023-1095] Linux kernel netfilter subsystem.: In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object
CVE-2023-1095Source published Source updated

A NULL pointer dereference flaw was found in the Linux kernel’s netfilter subsystem. This flaw allows a local, unprivileged user to crash the system, resulting in a denial of service. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-476. Affected Red Hat products: Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 8.1 Update Services for SAP Solutions; Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support; Red Hat Enterprise Linux 8.4…
