Description:
 The paging_invlpg function in include/asm-x86/paging.h in Xen 3.3.x through
 4.6.x, when using shadow mode paging or nested virtualization is enabled,
 allows local HVM guest users to cause a denial of service (host crash) via
 a non-canonical guest address in an INVVPID instruction, which triggers a
 hypervisor bug check.
