Assigned:2011-08-12
Published:2011-08-12
Updated:2012-12-13
Summary:Xen 4.1.1 and earlier allows local guest OS kernels with control of a PCI[E] device to cause a denial of service (CPU consumption and host hang) via many crafted DMA requests that are denied by the IOMMU, which triggers a livelock.
