Fix Version: 5.0.1.22

Description

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.
