  "title": "media: vivid: check for vb2_is_busy() when toggling caps",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  media: vivid: check for vb2_is_busy() when toggling caps  The vivid_update_format_cap/out() functions must only be called if the capture/output queue are not busy. But for the controls that select the CROP/COMPOSE/SCALE capability that is not checked.  Only when streaming starts will they be set to \u0027grabbed\u0027 and it is impossible to change the control, but between REQBUFS and STREAMON you are still allowed to set these controls. Since vivid_update_format_cap/out will change the format, this can cause unexpected results.  Besides adding these checks, also add a WARN_ON in vivid_update_format_cap/out() if the queue is busy.  I\u0027m 90% certain that this is the cause of this syzbot bug:  https://syzkaller.appspot.com/bug?extid=dac8f5eaa46837e97b89  But since we never have reproducers, it is hard to be certain. In any case, these checks are needed regardless.",
