CVE-2017-9715

Vulnerability

In Android for MSM, Firefox OS for MSM, QRD Android, and all Android releases from CAF using the Linux kernel, a buffer over-read can occur while processing a vendor command. This issue affects devices built with affected Qualcomm components and is addressed in the October 2017 Android security bulletin for Pixel/Nexus devices [1].

Exploitation

An attacker must be able to send a specially crafted vendor command to the device. No authentication or user interaction is required, and the attack can be performed locally (i.e., from an app or process with access to the vendor command interface). The exact sequence of steps involves crafting a command that triggers the out-of-bounds read operation [1].

Impact

Successful exploitation could allow an attacker to read sensitive kernel memory, leading to information disclosure. This may expose security-critical data such as cryptographic keys or memory contents, potentially escalating the attacker's capabilities [1].

Mitigation

The issue was fixed in the October 2017 Pixel/Nexus Security Bulletin. Users should apply Android security updates dated 2017-10-05 or later. No workarounds are provided; updating to the latest security patch level is the recommended mitigation [1].
