This is a note to let you know that I have just added a patch titled iio: accel: sca3000: memory corruption in sca3000_read_first_n_hw_rb() to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt20. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 83f14f99e360ec21fd19b4f669d21cbec93ef2cd Mon Sep 17 00:00:00 2001 From: Dan Carpenter <dan.carpenter@oracle.com> Date: Sat, 8 Aug 2015 22:16:42 +0300 Subject: iio: accel: sca3000: memory corruption in sca3000_read_first_n_hw_rb() commit eda7d0f38aaf50dbb2a2de15e8db386c4f6f65fc upstream. "num_read" is in byte units but we are write u16s so we end up write twice as much as intended.
