When pvr2_hdw_create returns back to pvr2_context_create, -it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL, -which leads to that pvr2_hdw_destroy directly returns. - -Fix this by adding v4l2_device_unregister to decrease the refcount of -usb interface. - -Reported-by: syzbot+77b432d57c4791183ed4@syzkaller.appspotmail.com -Signed-off-by: Dongliang Mu <mudongliangabcd@gmail.com> -Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> -Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org> -Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> ---- - drivers/media/usb/pvrusb2/pvrusb2-hdw.c | 1 + - 1 file changed, 1 insertion(+) - -diff --git a/drivers/media/usb/pvrusb2/pvrusb2-hdw.c b/drivers/media/usb/pvrusb2/pvrusb2-hdw.c -index a9666373af6b..92d6db1ad00f 100644 ---- a/drivers/media/usb/pvrusb2/pvrusb2-hdw.c -+++ b/drivers/media/usb/pvrusb2/pvrusb2-hdw.c -@@ -2610,6 +2610,7 @@ struct pvr2_hdw *pvr2_hdw_create(struct usb_interface *intf, - del_timer_sync(&hdw->encoder_run_timer); - del_timer_sync(&hdw->encoder_wait_timer); - flush_work(&hdw->workpoll); -+ v4l2_device_unregister(&hdw->v4l2_dev); - usb_free_urb(hdw->ctl_read_urb); - usb_free_urb(hdw->ctl_write_urb); - kfree(hdw->ctl_read_buffer); --- -2.37.3 - |
