From 359f90982cba0ba8db39b683de05dcb2de64b979 Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Tue, 1 Nov 2011 09:40:07 +0100 Subject: [PATCH] ALSA: hda_hwdep: Fix possible buffer overflow If a line in the firmware file is larger than the given buffer size (and so the firmware file size), size is set to a value larger than the actual buffer size. This results in an overflow in the buffer passed.
