nasa-mapper is like every other driver mapper except the driver is not mapped into the kernel, only specific contexts/processes you decide to map the driver into. nasa-mapper is like every other driver mapper except the driver is not mapped into the kernel, only specific contexts/processes you decide to map the driver into.
There are limitations to this driver mapper. Firstly your driver is not going to be globally mapped. Its only going to be accessable from inside of your context.
You can still call kernel functions, but you cannot switch contexts. In other words do not call `KeStackAttachProcess` directly. You can call MmCopyVirtualMemory though
since the context switch will happen inside of `ntoskrnl` which is globally mapped.

I guess you can call this physmeme v2? You can use any driver that exposes physical memory read/write with this driver mapper, simply replace the vulnerable driver inside of raw_driver.hpp.
