TIMELINE Sep 2 Reserved by mitre Sep 2 Published (CNA: mitre) Oct 14 ENRICHED — CVE-2022-39188. Received CVSS 4.7 and CPE data from NVD.
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.
