Subject: CVE-2022-49165: media: imx-jpeg: Prevent decoding NV12M jpegs into single-planar buffers

Description
===========

In the Linux kernel, the following vulnerability has been resolved:

media: imx-jpeg: Prevent decoding NV12M jpegs into single-planar buffers

If the application queues an NV12M jpeg as output buffer, but then
queues a single planar capture buffer, the kernel will crash with
"Unable to handle kernel NULL pointer dereference" in mxc_jpeg_addrs,
prevent this by finishing the job with error.

The Linux kernel CVE team has assigned CVE-2022-49165 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
