cpu_physical_memory_write() writes to the guest address space, so it won't overflow. If you ask it to write off the end of a ROM then it will correctly write into an unassigned part of the guest memory space (which does nothing) or into whatever device or other ram is there. You probably don't want to do that, but it is not a buffer overflow. thanks -- PMM
