CVE-2025-21985

CVE-2025-21985 : In the Linux kernel DRM/AMD display path, the fix addresses out-of-bounds accesses. Specifically, hpo_stream_to_link_encoder_mapping is sized MAX_HPO_DP2_ENCODERS(=4) but can reference up to 6 elements, so the location must be checked against MAX_HPO_DP2_ENCODERS. Also, disp_cfg_...
