Vulnerability from fkie_nvd - Published: 2022-09-02 05:15 - Updated: 2026-06-17 04:57
Severity
Summary
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.
