Subject: [patch] staging: csr: info leak in unifi_cfg_get_info()
Date: Thu, 04 Apr 2013 06:31:24 +0000	[thread overview]
Message-ID: <20130404063124.GB6494@longonot.mountain> (raw)

"cfg_ap_config" has a number of fields which are not cleared before we
copy them to the user.  I've added a memset() at the beginning to set
everything to zero.
