An update for kernel is now available for openEuler-20.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1341 Final 1.0 1.0 2021-09-13 Initial 2021-09-13 2021-09-13 openEuler SA Tool V1.0 2021-09-13 kernel security update An update for kernel is now available for openEuler-20.03-LTS. The Linux Kernel, the operating system core itself. Security Fix(es): A flaw was found in the Routing decision classifier in the Linux kernel s Traffic Control networking subsystem in the way it handled changing of classification filters, leading to a use-after-free condition. This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat from this vulnerability is confidentiality, integrity, as well as system availability.(CVE-2021-3715) An update for kernel is now available for openEuler-20.03-LTS. openEuler Security has rated this update as having a security impact of high.
