Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
media: nxp: imx8-isi: Fix streaming cleanup on release
The current implementation unconditionally calls mxc_isi_video_cleanup_streaming() in mxc_isi_video_release(). This can lead to situations where any release call (like from a simple "v4l2-ctl -l") may release a currently streaming queue when called on such a device.
This is reproducible on an i.MX8MP board by streaming from an ISI capture device using gstreamer:
gst-launch-1.0 -v v4l2src device=/dev/videoX ! \
video/x-raw,format=GRAY8,width=1280,height=800,framerate=1/120 ! \
fakesink
While this stream is running, querying the caps of the same device provokes the error state:
v4l2-ctl -l -d /dev/videoX
This results in the following trace:

Address this issue by moving the streaming preparation and cleanup to the vb2 .prepare_streaming() and .unprepare_streaming() operations. This also simplifies the driver by allowing direct usage of the vb2_ioctl_streamon() and vb2_ioctl_streamoff() helpers, and removal of the manual cleanup from mxc_isi_video_release().
