It implies that each driver should turn off the stream +properly after the drain. Meanwhile, USB-audio MIDI interface didn't +change the port->active flag after the drain. This may leave the +output work picking up the port that is closed right now, which +eventually leads to a use-after-free for the already released rawmidi +object. + +This patch fixes the bug by properly clearing the port->active flag +after the output drain. + +Reported-by: syzbot+70e777a39907d6d5fd0a@syzkaller.appspotmail.com +Cc: +Link: https://lore.kernel.org/r/00000000000011555605dceaff03@google.com +Link: https://lore.kernel.org/r/20220420130247.22062-1-tiwai@suse.de +Signed-off-by: Takashi Iwai +Signed-off-by: Greg Kroah-Hartman +--- + sound/usb/midi.c | 1 + + 1 file changed, 1 insertion(+) + +--- a/sound/usb/midi.c ++++ b/sound/usb/midi.c +@@ -1194,6 +1194,7 @@ static void snd_usbmidi_output_drain(str + } while (drain_urbs && timeout); + finish_wait(&ep->drain_wait, &wait); + } ++ port->active = 0; + spin_unlock_irq(&ep->buffer_lock); + } + diff --git a/queue-5.15/series b/queue-5.15/series index 98275c35715..5b92244833c 100644 --- a/queue-5.15/series +++ b/queue-5.15/series @@ -12,3 +12,5 @@ mm-kfence-support-kmem_dump_obj-for-kfence-objects.patch gfs2-assign-rgrp-glock-before-compute_bitstructs.patch scsi-ufs-core-scsi_get_lba-error-fix.patch net-sched-cls_u32-fix-netns-refcount-changes-in-u32_change.patch +alsa-usb-audio-clear-midi-port-active-flag-after-draining.patch +alsa-hda-realtek-add-quirk-for-clevo-np70pnp.patch
