## Overview

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

drm/omap: dsi: Do not copy isr table

To be able to unregister stuff from isrs, the corresponding table was
copied.  Nobody seems to unregister stuff that way, so it does not help.
But there are stack-allocated objects passed to these isrs giving chances
of UAF of these objects if irqs are unregistered while they are handled,
so better do not copy that table.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
