CVE-2014-8369
Published: 10 November 2014
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.
From the Ubuntu Security Team
The KVM (kernel virtual machine) subsystem of the Linux kernel miscalculates the number of memory pages during the handling of a mapping failure. A guest OS user could exploit this to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges.
