CVE-2017-0505 is an elevation of privilege vulnerability affecting multiple MediaTek kernel drivers on Android devices, including the M4U, sound, touchscreen, GPU, and Command Queue drivers. A local malicious application can exploit this vulnerability to execute arbitrary code with kernel privileges, leading to a full device compromise. The vulnerability is critical as it allows attackers to gain persistent root access, potentially requiring a full OS reflash to remediate.

This repository contains a proof-of-concept (POC) exploit for CVE-2017-0505, a vulnerability in the MediaTek M4U driver on Android devices. The main exploit code is in 'cve-2017-0505.c', which opens the device file '/proc/m4u' and sends a crafted ioctl call with a specific payload. The Makefile and Android.mk files provide build instructions for compiling the exploit as an Android native executable for the arm64-v8a architecture. The exploit must be run locally on a vulnerable Android device and does not provide a shell or further payload, but demonstrates the ability to trigger the vulnerability. The only fingerprintable endpoint is the '/proc/m4u' device file, which is specific to devices with the MediaTek M4U driver.
