Message-Id: <1447370309-357-100-git-send-email-kamal@canonical.com> Date: Thu, 12 Nov 2015 15:17:33 -0800 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Dan Carpenter <dan.carpenter@...cle.com>, Jonathan Cameron <jic23@...nel.org>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.19.y-ckt 099/155] iio: accel: sca3000: memory corruption in sca3000_read_first_n_hw_rb() 3.19.8-ckt10 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Dan Carpenter <dan.carpenter@...cle.com> commit eda7d0f38aaf50dbb2a2de15e8db386c4f6f65fc upstream. "num_read" is in byte units but we are write u16s so we end up write twice as much as intended.
