Subject: [patch 06/24] USB: fix array overrun in drivers/usb/serial/option.c
Date: Thu, 27 Apr 2006 17:18:04 -0700	[thread overview]
Message-ID: <20060428001804.GG18750@kroah.com> (raw)
In-Reply-To: <20060428001557.GA18750@kroah.com>

[-- Attachment #1: usb-fix-array-overrun-in-drivers-usb-serial-option.c.patch --]
[-- Type: text/plain, Size: 1404 bytes --]

-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Eric Sesterhenn <snakebyte@gmx.de>

since the arrays are declared as in_urbs[N_IN_URB]
and out_urbs[N_OUT_URB] both for loops, go one
over the end of the array. This fixes coverity id #555

This patch was already included in Linus' tree.
