On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

DESCRIPTION

* CVE-2012-2121: Memory leak in KVM device assignment.

KVM uses memory slots to track and map guest regions of memory.  When device
assignment is used, the pages backing these slots are pinned in memory and mapped
into the iommu.  The problem is that when a memory slot is destroyed the pages
for the associated memory slot are neither unpinned nor unmapped from the iommu.
