sound: sequencer: cap array index in seq_chn_common_event()
"chn" here is a number between 0 and 255, but ->chn_info only has 16 elements so there is a potential write beyond the end of the array. If the seq_mode isn't SEQ_2 then we let the individual drivers (either opl3.c or midi_synth.c) handle it. Those functions all do a bounds check on "chn" so I haven't changed anything here. The opl3.c driver has up to 18 channels and not 16. Signed-off-by: Dan Carpenter <firstname.lastname@example.org> Signed-off-by: Takashi Iwai <email@example.com>
