Description

media: nxp: imx8-isi: Fix streaming cleanup on release

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().

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
