Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd/display: Fix null check of pipe_ctx-&gt;plane_state for update_dchubp_dpp<br /> <br /> Similar to commit 6a057072ddd1 ("drm/amd/display: Fix null check for<br /> pipe_ctx-&gt;plane_state in dcn20_program_pipe") that addresses a null<br /> pointer dereference on dcn20_update_dchubp_dpp. This is the same<br /> function hooked for update_dchubp_dpp in dcn401, with the same issue.<br /> Fix possible null pointer deference on dcn401_program_pipe too.<br /> <br /> (cherry picked from commit d8d47f739752227957d8efc0cb894761bfe1d879)
