|Bugzilla:||910903: CVE-2013-0153 kernel: xen: interrupt remap entries shared and old ones not cleared on AMD IOMMUs|
The MITRE CVE dictionary describes this issue as:
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.
This issue did affect the versions of the kernel-xen package as shipped with Red Hat Enterprise Linux 5.
This issue did not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2.
