Description

ALSA: usb-audio: Fix potential memory leaks at error path for UMP open

In the Linux kernel, the following vulnerability has been resolved:

ALSA: usb-audio: Fix potential memory leaks at error path for UMP open

The allocation and initialization errors at alloc_midi_urbs() that is

called at MIDI 2.0 / UMP device are supposed to be handled at the

caller side by invoking free_midi_urbs(). However, free_midi_urbs()

loops only for ep->num_urbs entries, and since ep->num_entries wasn't

updated yet at the allocation / init error in alloc_midi_urbs(), this

entry won't be released.

The intention of free_midi_urbs() is to release the whole elements, so

change the loop size to NUM_URBS to scan over all elements for fixing

the missed releases.

Also, the call of free_midi_urbs() is missing at

snd_usb_midi_v2_open(). Although it'll be released later at

reopen/close or disconnection, it's better to release immediately at

the error path.
