An update for kernel is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1729 Final 1.0 1.0 2023-10-13 Initial 2023-10-13 2023-10-13 openEuler SA Tool V1.0 2023-10-13 kernel security update An update for kernel is now available for openEuler-22.03-LTS. The Linux Kernel, the operating system core itself. Security Fix(es): An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.(CVE-2023-42753) An update for kernel is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high.
