CVE-2014-3186

Published: 28 September 2014

Buffer overflow in the picolcd_raw_event function in devices/hid/hid-picolcd_core.c in the PicoLCD HID device driver in the Linux kernel through 3.16.3, as used in Android on Nexus 7 devices, allows physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that sends a large report.

From the Ubuntu security team

Steven Vittitoe reported a buffer overflow in the Linux kernel's PicoLCD HID device driver. A physically proximate attacker could exploit this flaw to cause a denial of service (system crash) or possibly execute arbitrary code via a specially craft device.
