[Linux-stable-mirror] [PATCH 0/3] ALSA: usb-audio: fix OOB and return value check

Hi,

This patch series fixes the out-of-bound error caused by the return value of usb_string(). It was descovered by KASAN. The Patch 1 is the V2 about http://www.spinics.net/lists/alsa-devel/msg69487.html

Chanes in V2: - put an explicit error bail out(by Takashi iwai)

Patch1 was founded by connecting the following product. http://www.lg.com/uk/lg-friends/lg-AFD-1200

I found that it only check if the return value from usb_string() is always zero while modifying OOB KASAN message. So instead of making the modifications to OOB to V2, I sent a patch series.

I am sorry to break the mail thread.

Thanks jaejoong
