In the Linux kernel, the following vulnerability has been resolved:
drm/shmem_helper: Check VMA boundaries for PMD mappings
In the ->huge_fault handler do not install a PMD huge page

All other ->huge_fault handlers have similar checks and the
resulting mapping will trigger a VM_BUG_ON_VMA() if it ever
reaches copy_pmd_range().
