This is a note to let you know that I have just added a patch titled ext4: fix potential integer overflow to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt5. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 4.2.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From 8a26972a570984580448bc71e492779dff6c03b8 Mon Sep 17 00:00:00 2001 From: Insu Yun <wuninsu@gmail.com> Date: Fri, 12 Feb 2016 01:15:59 -0500 Subject: ext4: fix potential integer overflow commit 46901760b46064964b41015d00c140c83aa05bcf upstream. Since sizeof(ext_new_group_data) > sizeof(ext_new_flex_group_data), integer overflow could be happened. Therefore, need to fix integer overflow sanitization.
