DESCRIPTION:
A vulnerability has been reported in Xen, which can be exploited by
malicious, local users in a guest virtual machine to cause a DoS
(Denial of Service).
The vulnerability is caused due to an error within the Xen AMD IOMMU
feature when handling interrupt remap entries, which can be exploited
to inject interrupts into other guests e.g. domain 0 and cause a
crash.
Successful exploitation requires a guest with AMD-Vi for PCI
passthrough.
The vulnerability is reported in versions 3.3 and later.
SOLUTION:
Apply patches if available.
