CVE-2025-21985
HIGHLinux Kernel 4.15-6.12.19, 6.13.0-6.13.7 - Out-of-bounds Read in DRM AMD Display Stream Mapping
Title source: llmDescription
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix out-of-bound accesses [WHAT & HOW] hpo_stream_to_link_encoder_mapping has size MAX_HPO_DP2_ENCODERS(=4), but location can have size up to 6. As a result, it is necessary to check location against MAX_HPO_DP2_ENCODERS. Similiarly, disp_cfg_stream_location can be used as an array index which should be 0..5, so the ASSERT's conditions should be less without equal.
