CVE-2014-3601
Published: 31 August 2014
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.
From the Ubuntu security team
Jack Morgenstein reported a flaw in the page handling of the KVM (Kerenl Virtual Machine) subsystem in the Linux kernel. A guest OS user could exploit this flaw to cause a denial of service (host OS memory corruption) or possibly have other unspecified impact on the host OS.
