How to fix?

Upgrade Debian:11 linux-6.1 to version 6.1.129-1~deb11u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-6.1 package and not the linux-6.1 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

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

media: imx-jpeg: Fix potential error pointer dereference in detach_pm()

The proble is on the first line:

if (jpeg-&gt;pd_dev[i] &amp;&amp; !pm_runtime_suspended(jpeg-&gt;pd_dev[i]))

If jpeg->pd_dev[i] is an error pointer, then passing it to pm_runtime_suspended() will lead to an Oops. The other conditions check for both error pointers and NULL, but it would be more clear to use the IS_ERR_OR_NULL() check for that.
