An update for kernel is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1469 Final 1.0 1.0 2021-12-24 Initial 2021-12-24 2021-12-24 openEuler SA Tool V1.0 2021-12-24 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. The Linux Kernel, the operating system core itself. Security Fix(es): A read-after-free memory flaw was found in the Linux kernel s garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.(CVE-2021-4083) An update for kernel is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. openEuler Security has rated this update as having a security impact of high. 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.
