CVE-2012-2121

Priority
Description
The KVM implementation in the Linux kernel before 3.3.4 does not properly
manage the relationships between memory slots and the iommu, which allows
guest OS users to cause a denial of service (memory leak and host OS crash)
by leveraging administrative access to the guest OS to conduct hotunplug
and hotplug operations on devices.
Ubuntu-Description
A flaw was discovered in the Linux kernel's KVM (kernel virtual machine).
An administrative user in the guest OS could leverage this flaw to cause a
denial of service in the host OS.
