In the Linux kernel, the following vulnerability has been resolved:
ALSA: usx2y: us144mkii: fix NULL deref on missing interface 0
A malicious USB device with the TASCAM US-144MKII device id can have a
configuration containing bInterfaceNumber=1 but no interface 0. USB
configuration descriptors are not required to assign interface numbers
sequentially, so usb_ifnum_to_if(dev, 0) returns will NULL, which will
then be dereferenced directly.
Fix this up by checking the return value properly.
