** Description changed:
- Linux kernel iommu.c excessive unpinning
+ 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.
