An update for kernel is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1968 Final 1.0 1.0 2022-09-30 Initial 2022-09-30 2022-09-30 openEuler SA Tool V1.0 2022-09-30 kernel security update An update for kernel is now available for openEuler-22.03-LTS. The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.(CVE-2022-39188) An update for kernel is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of medium.
