CVE-2013-4329

The xenlight library libxl in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction...

libxl partially sets up HVM passthrough even with disabled iommu

ISSUE DESCRIPTION With HVM domains, libxl's setup of PCI passthrough devices does the IOMMU setup after giving via the device model the guest access to the hardware and advertising it to the guest. If the IOMMU is disabled the overall setup fails, but after the device has been made available to t...
