The do_mmu_update function in arch/x86/mm.c in Xen 4.x through 4.4.x does not properly restrict updates to only PV page tables, which allows remote PV guests to cause a denial of service (NULL pointer dereference) by leveraging hardware emulation services for HVM guests using Hardware Assisted Paging (HAP).

CVE-2014-8594 [MEDIUM] CVE-2014-8594 kernel: xen: Insufficient restrictions on certain MMU update hypercalls (xsa109)
CVE-2014-8594 kernel: xen: Insufficient restrictions on certain MMU update hypercalls (xsa109)
MMU update operations targeting page tables are intended to be used on
PV guests only. The lack of a respective check made it possible for
such operations to access certain function pointers which remain NULL
when the target guest is using Hardware Assisted Paging (HAP).
Malicious or buggy stub domain kernels or tool stacks otherwise living
outside of Domain0 can mount a denial of service attack which, if
successful, can affect the whole system.

Red Hat would like to thank the Xen for reporting this issue.
