CVE-2013-4329 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
