3.19.8-ckt10 -stable review patch. If anyone has any objections, please let me know. ------------------ From: =?UTF-8?q?Salva=20Peir=C3=B3?= <speirofr@xxxxxxxxx> 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.
