An update for kernel is now available for openEuler-20.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1844 Final 1.0 1.0 2022-08-19 Initial 2022-08-19 2022-08-19 openEuler SA Tool V1.0 2022-08-19 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP3. Security Fix(es): The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges.(CVE-2022-36123) In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-223375145References: Upstream kernel(CVE-2022-20369) An update for kernel is now available for openEuler-20.03-LTS-SP3. openEuler Security has rated this update as having a security impact of medium.
