** Changed in: linux-lts-quantal (Ubuntu Precise)
       Status: New => Fix Committed

** Changed in: linux-ti-omap4 (Ubuntu Precise)
       Status: New => Fix Committed

** Description changed:

- [kvm: invalid parameter passing in kvm_iommu_map_pages()]
+ The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel
+ through 3.16.1 miscalculates the number of pages during the handling of
+ a mapping failure, which allows guest OS users to (1) cause a denial of
+ service (host OS memory corruption) or possibly have unspecified other
+ impact by triggering a large gfn value or (2) cause a denial of service
+ (host OS memory consumption) by triggering a small gfn value that leads
+ to permanently pinned pages.
