From: Salva Peiró <speirofr@xxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== commit 4b6184336ebb5c8dc1eae7f7ab46ee608a748b05 upstream. The dgnc_mgmt_ioctl() code fails to initialize the 16 _reserved bytes of struct digi_dinfo after the ->dinfo_nboards member. Add an explicit memset(0) before filling the structure to avoid the info leak.
