The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors.

CVE-2012-4538 kernel: xen: Unhooking empty PAE entries can crash Xen
The HVMOP_pagetable_dying hypercall does not correctly check the caller's pagetable state, leading to a hypervisor crash.
An HVM guest running on shadow pagetables (that is, not HAP) can cause the hypervisor to crash.
Acknowledgements:
Red Hat would like to thank the Xen project for reporting this issue.
