*** This bug is a security vulnerability ***

Public security bug reported:

The guest_walk_tables function in arch/x86/mm/guest_walk.c in Xen 4.6.x
and earlier does not properly handle the Page Size (PS) page table entry
bit at the L4 and L3 page table levels, which might allow local guest OS
users to gain privileges via a crafted mapping of memory.
