Hi

>From the XSA-207:


ISSUE DESCRIPTION
=================

Certain internal state is set up, during domain construction, in
preparation for possible pass-through device assignment.  On ARM and
AMD V-i hardware this setup includes memory allocation.  On guest
teardown, cleanup was erroneously only performed when the guest
actually had a pass-through device assigned.

AFAIK, no CVE is assigned yet to the issue.
