CVE-2013-0153

Status Candidate

Overview

The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests.

Red Hat Security Advisory 2013-0847-01

Red Hat Security Advisory 2013-0847-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Xen hypervisor AMD IOMMU driver handled interrupt remapping entries. By default, a single interrupt remapping table is used, and old interrupt remapping entries are not cleared, potentially allowing a privileged guest user in a guest that has a passed-through, bus-mastering capable PCI device to inject interrupt entries into others guests, including the privileged management domain, leading to a denial of service.
