This is a note to let you know that I have just added a patch titled hamradio/yam: fix info leak in ioctl to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.16. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 3c8e9c002b04a4f2030fe49039e0c1d787329e18 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Salva=20Peir=C3=B3?= <speiro@ai2.upv.es> Date: Tue, 17 Dec 2013 10:06:30 +0100 Subject: hamradio/yam: fix info leak in ioctl MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 8e3fbf870481eb53b2d3a322d1fc395ad8b367ed ] The yam_ioctl() code fails to initialise the cmd field of the struct yamdrv_ioctl_cfg. Add an explicit memset(0) before filling the structure to avoid the 4-byte info leak. Signed-off-by: Salva Peiró <speiro@ai2.upv.es> Signed-off-by: David S.
