A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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

drm/amd/display: Avoid DPMS-on for phantom stream

[Why & How] Calling dc_update_planes_and_stream separately for stream and its phantom stream causes a NULL pointer dereference, since the phantom is destroyed on the first call.

Skip the call for phantom streams.
