Description Prasad Pandit 2014-09-13 02:29:45 UTC

Linux kernel built with the Human Interface Device(HID) Bus support(CONFIG_HID)
along with a driver for Minibox PicoLCD devices support(CONFIG_HID_PICOLCD),
is vulnerable to an OOB write flaw. It could occur if a device offers an HID
report with arbitrary(>64) data size value.

A local user with physical access to the system could use this flaw to crash
the system resulting in DoS or potentially, escalate their privileges on the
system.

Upstream fix:
