CVE request: Linux kernel: Bluetooth HIDP information disclosure
From: P J P <ppandit () redhat com>
Date: Fri, 22 Feb 2013 15:35:20 +0530 (IST)


Linux kernel built with Bluetooth stack and HIDP support HCONFIG_BT=y/m & CONFIG_BT_HIDP=y/m is vulnerable to an information disclosure flaw caused by wrongly initializing the hid_device->name, physical location and unique identifier variables. Information leakage happens if these variables are not NULL('\0') terminated.

An unprivileged user/program could cause this via ioctl(HIDPCONNADD) call.

Upstream fix:
 -> https://git.kernel.org/linus/0a9ab9bdb3e891762553f667066190c1d22ad62b

 -> https://bugzilla.redhat.com/show_bug.cgi?id=914298

Thank you.
