CVE-2024-43886 Information

Description

In the Linux kernel the following vulnerability has been resolved:

drm/amd/display: Add null check in resource_log_pipe_topology_update

[WHY] When switching from \Extend\ to \Second Display Only\ we sometimes call resource_get_otg_master_for_stream on a stream for the eDP which is disconnected. This leads to a null pointer dereference.

[HOW] Added a null check in dc_resource.c/resource_log_pipe_topology_update.
