一、漏洞信息
漏洞编号：CVE-2022-39188
漏洞归属组件：kernel
漏洞归属的版本：4.19, 5.10
CVSS V3.0分值：
BaseScore：4.7 Medium
Vector：CVSS：3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
漏洞简述：
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.
