Title
drm/amd/display: Fix index out of bounds in DCN30 color transformation
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix index out of bounds in DCN30 color transformation This commit addresses a potential index out of bounds issue in the `cm3_helper_translate_curve_to_hw_format` function in the DCN30 color management module. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, the function returns false to indicate an error. drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:180 cm3_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:181 cm3_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:182 cm3_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max
