## Build & Run

In order to build, run Android NDK's `ndk-build`.

In order to run the PoC, run the binary using the following command:

    LD_PRELOAD=libQSEEComAPI.so ./qseecom_uaf

Make sure to run it from a context where `/dev/qseecom` is accessible.

## Result

Running this on a Pixel 3 running Android 9 causes the kernel to panic. In
theory this PoC should work on other Android devices and versions without any
modifications but I have not tested it.
