CVE-2017-15592 xsa243 xen: x86: Incorrect handling of self-linear shadow mappings with translated guests (XSA-243)
ISSUE DESCRIPTION
The shadow pagetable code uses linear mappings to inspect and modify the
shadow pagetables. A linear mapping which points back to itself is known as
self-linear. For translated guests, the shadow linear mappings (being in a
separate address space) are not intended to be self-linear. For
non-translated guests, the shadow linear mappings (being the same
address space) are intended to be self-linear.
When constructing a monitor pagetable for Xen to run on a vcpu with, the shadow
linear slot is filled with a self-linear mapping, and for translated guests,
shortly thereafter replaced with a non-self-linear mapping, when the guest's
%cr3 is shadowed.
