A use-after-free vulnerability exists in the Qualcomm Secure Execution Environment (QSEE) implementation on multiple Snapdragon SoCs. The flaw is due to improper memory management, where memory is used after it has been freed, potentially allowing execution of arbitrary or unknown code. This affects a wide range of Snapdragon platforms across Auto, Compute, Consumer IoT, Industrial IoT, Mobile, Voice & Music, and Wearables product lines.

This repository is a proof-of-concept (PoC) exploit for CVE-2019-14040, a use-after-free vulnerability in Qualcomm's QSEECom/ION kernel drivers affecting Android devices. The main exploit code is in 'jni/qseecom_uaf.c', which demonstrates how to trigger the vulnerability by manipulating ION memory buffers and interacting with the QSEECom device node. The exploit is designed to be built with the Android NDK and run on a vulnerable device with access to /dev/qseecom and /dev/ion. When executed, it causes a kernel panic, demonstrating a denial-of-service condition. The repository includes several header files for interacting with the relevant kernel interfaces and a Makefile for building the PoC. No remote or network attack vector is present; the exploit requires local code execution on the target device. The PoC does not provide privilege escalation or shell access, but serves as a demonstrative crash to aid in vulnerability verification and research.
