An update for kernel is now available for openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1864 Final 1.0 1.0 2022-08-26 Initial 2022-08-26 2022-08-26 openEuler SA Tool V1.0 2022-08-26 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP1. The Linux Kernel, the operating system core itself. Security Fix(es): Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.(CVE-2022-26373) A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local, privileged attacker to crash the system, possibly leading to a local privilege escalation issue.(CVE-2022-2588) An update for kernel is now available for openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
