This is a note to let you know that I have just added a patch titled serial: vt8500: Fix range-checking on vt8500_uart_ports 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 3.8.13.12. 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 8beb4c0b6218b9221cb1ca05993ce3e83fdd0fd8 Mon Sep 17 00:00:00 2001 From: Tony Prisk <linux@prisktech.co.nz> Date: Thu, 17 Jan 2013 08:05:40 +1300 Subject: serial: vt8500: Fix range-checking on vt8500_uart_ports commit 27dd2e04923341cff96aae164117c44da1072c32 upstream. Fix two instances where the index to vt8500_uart_ports is tested against > VT8500_MAX_PORTS. Correct usage should be >= VT8500_MAX_PORTS.
