CVE-2017-0709

Vulnerability

An information disclosure vulnerability exists in the HTC sensor hub driver of the Android kernel. The bug allows a local attacker to access sensitive kernel memory or sensor data. Affected versions include Android kernels prior to the security patch level of July 2017, as indicated in the Android Security Bulletin [1].

Exploitation

To exploit this vulnerability, an attacker requires local access to the device and the ability to interact with the HTC sensor hub driver. This could be achieved through a malicious application running in user space that sends crafted input to the driver, triggering the information leak.

Impact

Successful exploitation leads to the disclosure of sensitive information from the kernel or sensor hub, potentially revealing memory contents or sensor data that should be protected. The scope is limited to information disclosure, and no code execution or privilege escalation is reported.

Mitigation

Google released a fix as part of the July 2017 Android Security Bulletin [1]. Users should apply the Android security patch level 2017-07-05 or later to mitigate this vulnerability. No other workarounds are documented.
