CWE-362

Description

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.

Affected configurations

• linux linux kernel (< 5.19) • debian debian linux 10.0 • debian debian linux 11.0
