In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix late derefrence dsc check in link_set_dsc_pps_packet()
In link_set_dsc_pps_packet(), struct display_stream_compressor *dsc was dereferenced in a DC_LOGGER_INIT(dsc->ctx->logger); before the dsc NULL pointer check.
Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_dpms.c:905 link_set_dsc_pps_packet() warn: variable dereferenced before check dsc (see line 903)
