The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel
through 3.17.2 miscalculates the number of pages during the handling of a
mapping failure, which allows guest OS users to cause a denial of service
(host OS page unpinning) or possibly have unspecified other impact by
leveraging guest OS privileges. NOTE: this vulnerability exists because of
an incorrect fix for CVE-2014-3601.
