Subject[PATCH 3.4 105/134] ALSA: ak4xx-adda: info leak in ak4xxx_capture_source_info()
Date
3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit bd5fe738e388ceaa32e5171481e0d3ec59f0ccfe upstream.

"idx" is controled by the user and can be a negative offset into the
input_names[] array.
