CVE-2011-3131: Xen

Medium severity, CVSS 4.6. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
