CVE-2017-6247

Vulnerability

The vulnerability resides in the NVIDIA sound driver on Android devices. A local malicious application can trigger an elevation of privilege to execute arbitrary code within the kernel context. The specific affected driver versions are not listed in the available references, but the issue is addressed in the Android Security Bulletin for June 2017 [1].

Exploitation

An attacker must have the ability to install and run a malicious application on the target device. The application can then exploit the vulnerability by sending a crafted request to the NVIDIA sound driver, without requiring additional authentication or user interaction beyond installation.

Impact

Successful exploitation allows the attacker to execute arbitrary code in the kernel, resulting in full compromise of the device. This includes the ability to access sensitive data, modify system settings, and install persistent malware, all with kernel-level privileges.

Mitigation

The fix is included in the Android Security Bulletin dated June 2017 [1]. Users should ensure their device's security patch level is set to 2017-06-01 or later. No workaround is available; applying the update is the recommended mitigation.
