Problem Description:

The bounds checking of accesses to guest memory greater + than 4GB by device emulations is subject to integer + overflow.

Impact:

For a bhyve virtual machine with more than 3GB of guest + memory configured, a malicious guest could craft device + descriptors that could give it access to the heap of the + bhyve process. Since the bhyve process is running as root, + this may allow guests to obtain full control of the hosts + they're running on.
