kernel: xen: interrupt remap entries shared and old ones not cleared on AMD IOMMUs

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...

CVE-2013-1952

Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service interrupt injection via unspecified vector...

DEBIAN-CVE-2013-1919

Xen 4.2.x and 4.1.x does not properly restrict access to IRQs, which allows local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to "passed-through IRQs or PCI devices."...

CVE-2013-1952

CVE-2013-1952 affects Xen 4.x when using Intel VT-d for bus-master PCI devices. The vulnerability is a flaw in validating the source while accessing a bridge device’s interrupt remapping table entries for MSI interrupts, which can allow a local guest domain to cause a denial of service via interr...

VT-d interrupt remapping source validation flaw for bridges

ISSUE DESCRIPTION Interrupt remapping table entries for MSI interrupts set up by bridge devices did not get any source validation set up on them, allowing misbehaving or malicious guests to inject interrupts into the domain owning the bridges. In a typical Xen system bridge devices are owned by...
