It's unreasonable to use 0 as the power1_min_cap when OD is disabled. So, use the same lower limit as the value used when OD is enabled.

drm/amd/display: Prevent potential buffer overflow in map_hw_resources

2024-02-27T17:20:42Z

Adds a check in the map_hw_resources function to prevent a potential buffer overflow. The function was accessing arrays using an index that could potentially be greater than the size of the arrays, leading to a buffer overflow. Adds a check to ensure that the index is within the bounds of the arrays. If the index is out of bounds, an error message is printed and break it will continue execution with just ignoring extra data early to prevent the buffer overflow. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml2_wrapper.c:79 map_hw_resources() error: buffer overflow 'dml2->v20.scratch.dml_to_dc_pipe_mapping.disp_cfg_to_stream_id' 6 <= 7 drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml2_wrapper.c:81 map_hw_resources() error: buffer overflow 'dml2->v20.scratch.dml_to_dc_pipe_mapping.disp_cfg_to_plane_id' 6 <= 7 Fixes: 7966f319c66d ("drm/amd/display: Introduce DML2") Cc: Rodrigo Siqueira Cc: Roman Li Cc: Qingqing Zhuo Cc: Aurabindo Pillai Cc: Tom Chung Signed-off-by: Srinivasan Shanmugam Suggested-by: Roman Li Reviewed-by: Roman Li Reviewed-by: Rodrigo Siqueira Signed-off-by: Alex Deucher
