The issue could occur when the index 'i' exceeds the\nnumber of transfer function points (TRANSFER_FUNC_POINTS).\n\nThe fix adds a check to ensure 'i' is within bounds before accessing the\ntransfer function points. If 'i' is out of bounds, the function returns\nfalse to indicate an error.\n\ndrivers/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\ndrivers/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\ndrivers/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\n\ud83d\udccf Published: 2024-10-21T18:02:19.044Z\n\ud83d\udccf Modified: 2025-05-16T07:25:05.887Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/7ab69af56a23859b647dee69fa1052c689343621\n2. https://git.kernel.org/stable/c/c13f9c62015c56a938304cef6d507227ea3e0039\n3. https://git.kernel.org/stable/c/0f1e222a4b41d77c442901d166fbdca967af0d86\n4. https://git.kernel.org/stable/c/929506d5671419cffd8d01e9a7f5eae53682a838\n5. https://git.kernel.org/stable/c/578422ddae3d13362b64e77ef9bab98780641631\n6. https://git.kernel.org/stable/c/b9d8b94ec7e67f0cae228c054f77b73967c389a3\n7. https://git.kernel.org/stable/c/d81873f9e715b72d4f8d391c8eb243946f784dfc", "creation_timestamp": "2025-05-16T07:34:04.000000Z"}
