CVE-2017-6249

Vulnerability

A vulnerability in the NVIDIA sound driver on Android devices can lead to an elevation of privilege. The flaw, identified as CVE-2017-6249, is present in the kernel-level driver and can be triggered by a local malicious application. The Android Security Bulletin for June 2017 notes that the issue is rated as Moderate because it first requires compromising a privileged process. The affected versions are not specified in the available sources, but the patch was included in the June 2017 Android security update [1].

Exploitation

Exploitation requires a local malicious application to first compromise a privileged process on the device. Once that initial foothold is gained, the attacker can leverage the sound driver vulnerability to execute arbitrary code within the kernel context. No additional user interaction is needed beyond the initial compromise [1].

Impact

Successful exploitation allows the attacker to execute arbitrary code in the kernel, resulting in a complete compromise of the device's security. This can lead to full control over the operating system, including access to sensitive data and the ability to install persistent malware [1].

Mitigation

Google released a security patch as part of the June 2017 Android Security Bulletin [1]. Users should apply the OTA update or install the corresponding patch level. No workarounds are documented; updating the device to the latest security patch level is the recommended mitigation.
