Subject: [patch 1/1] drivers/net/irda/irda-usb.c: fix buffer overflow
Date: Tue, 13 Jan 2009 13:30:54 -0800	[thread overview]
Message-ID: <200901132130.n0DLUsjq014237@imap1.linux-foundation.org> (raw)

From: Jos-Vicente Gilabert <josevteg@gmail.com>

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=12397

We're doing an sprintf of an 11-char string into an 11-char buffer. 
Whoops.  It breaks firmware uploading.
