Vulnerability details

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

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.
