Title:Qualcomm Adreno GPU缓冲区错误漏洞 (CVE-2020-11179)
Description:Arbitrary read and write to kernel addresses by temporarily overwriting ring buffer pointer and creating a race condition. in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables

Readme

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. 

current output: \
sunfish:/data/local/tmp $ ./adrenaline                                                                                              
starting adrenaline_rptr_child \
rptr base is 0xfc0df000 \
starting adrenaline \
starting adrenaline_parent \
starting adrenaline_child

test device: pixel 4a \
android 10 on build QD4A.2000317.027

**TODO:**
- work on context switch and race condition 
- to achieve kernel code exec
