From: Greg Kroah-Hartman <gregkh@...nel.org>

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

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

media: imx-jpeg: Disable useless interrupt to avoid kernel panic

There is a hardware bug that the interrupt STMBUF_HALF may be triggered
after or when disable interrupt.
It may led to unexpected kernel panic.
And interrupt STMBUF_HALF and STMBUF_RTND have no other effect.
So disable them and the unused interrupts.

meanwhile clear the interrupt status when disable interrupt.

The Linux kernel CVE team has assigned CVE-2022-50741 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:
