FreeBSD : xen-kernel -- x86 shadow pagetables: address width overflow (d51ced72-4212-11e6-942d-bc5ff45d0f28)

The Xen Project reports : In the x86 shadow pagetable code, the guest frame number of a superpage mapping is stored in a 32-bit field. If a shadowed guest can cause a superpage mapping of a guest-physical address at or above 2^44 to be shadowed, the top bits of the address will be lost, causing a...
