CVE-2021-1961 is a buffer overflow vulnerability in multiple Qualcomm Snapdragon product lines, including Auto, Compute, Connectivity, Consumer IOT, Industrial IOT, Mobile, Voice & Music, and Wearables. The vulnerability arises from a lack of proper offset length checking when updating buffer values, which can result in writing beyond the allocated buffer boundaries.

This repository contains a full exploit for CVE-2021-1961, targeting Android devices with Qualcomm TrustZone. The exploit is implemented in C and is intended to be built with the Android NDK. The main entry point is 'jni/main.c', which orchestrates the exploit steps. The exploit leverages a vulnerability in the QSEECom driver to achieve arbitrary kernel memory read and write. It demonstrates its capabilities by modifying the kernel's /proc/version and disabling SELinux enforcement. The code interacts with device files such as /dev/qseecom and /dev/ion, and uses the Widevine QSEECom app for cryptographic operations. The repository is well-structured, with separate files for each component (ION memory management, QSEECom API, exploit logic, symbol resolution, and Widevine interaction). The exploit requires local access with sufficient privileges to access /dev/qseecom, making it a local privilege escalation exploit. The payload is operational, providing real kernel modification capabilities, and is not just a proof-of-concept.
