An update for kernel is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1538 Final 1.0 1.0 2023-08-26 Initial 2023-08-26 2023-08-26 openEuler SA Tool V1.0 2023-08-26 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): A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to incorrect handling of the existing filter, leading to a kernel information leak issue.(CVE-2023-4128) 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.
