From 28aaf89cdfff86c498d0b5e2d07664e3a98a3280 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Sun, 17 Feb 2013 14:33:04 +0100 Subject: [PATCH] ALSA: usb/quirks, fix out-of-bounds access commit 4909a0caabb8b4352efcea223e58b86f8bc1f98b upstream. bootresponse in snd_usb_mbox2_boot_quirk is only 12 (decimal) u8's long, but i9s passed to snd_usb_ctl_msg as it would be 0x12 (hexa) long. Fix that by having proper size of the array, i.e. 0x12.
