"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 <dan.carpenter@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> |

The modular sound driver patches were funded by Red Hat Software (www.redhat.com). The sound driver here is thus a modified version of Hannu's code. Please bear that in mind when considering the appropriate forums for bug reporting. Alan Cox
