When overcommitting, the kernel will give you a range of virtual memory that isn't actually backed by physical memory. It will then map the memory as you access it. If you try to access too much of it and the kernel runs out of physical memory, it will kill the process. You can't use that mechanism to overwrite pieces of memory you didn't want to overwrite - or at least I don't see a way to do so.
