From 873156565ca67779bbf5a3475ccd08ea3bb92522 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/2] ALSA: usb-audio: Add sanity checks for endpoint accesses
Add some sanity check codes before actually accessing the endpoint via
get_endpoint() in order to avoid the invalid access through a
malformed USB descriptor. Mostly just checking bNumEndpoints, but in
one place (snd_microii_spdif_default_get()), the validity of iface and
altsetting index is checked as well.

Subject: [PATCH 1/2] ALSA: usb-audio: Fix NULL dereference in
create_fixed_stream_quirk()
create_fixed_stream_quirk() may cause a NULL-pointer dereference by
accessing the non-existing endpoint when a USB device with a malformed
USB descriptor is used.
This patch avoids it simply by adding a sanity check of bNumEndpoints
before the accesses.
