CVE-2022-39188: Race Condition

Published Sep 2, 2022
·
Updated

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmapmappingrange versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VMPFNMAP VMAs.
