Description Petr Matousek 2013-02-13 13:59:06 EST 
Xen's PCI backend drivers in Linux allow a guest with assigned PCI device(s) to cause a DoS through a flood of kernel messages, potentially affecting other
domains in the system.

A malicious guest with passed through PCI devices can mount a DoS affecting the entire system.

Acknowledgements:

Red Hat would like to thank the Xen project for reporting this issue.
