The Linux Kernel, the operating system core itself. Security Fix(es): In rcu_cblist_dequeue of rcu_segcblist.c, there is a possible use-after-free due to improper locking. This could lead to local escalation of privilege in the kernel with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-222091980References: Upstream kernel(CVE-2022-20153) 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.
