A high-severity vulnerability in the Linux kernel ALSA MIDI subsystem was resolved. The flaw involved improper serialization of input teardown with event_input, which could cause a kernel NULL pointer dereference and unexpected device activity. The issue occurs when snd_midi_input_event() runs while a rawmidi substream is closing, leading to a use-after-free or similar state corruption. The fix applies serialization and RCU mechanisms to prevent re-triggering of input events after teardown.
