The issue\ncould occur when the index 'i' exceeds the number of transfer function\npoints (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\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:594 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:595 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max\ndrivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:596 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max\n\n## Affected\n\n- `simatic_s7-1500_tm_mfp_firmware = 1.1`\n- `debian_linux = 11.0`\n- `linux_kernel >= 4.15, < 4.19.323`\n- `linux_kernel >= 4.20, < 5.4.285`\n- `linux_kernel >= 5.5, < 5.10.227`\n- `linux_kernel >= 5.11, < 5.15.168`\n- `linux_kernel >= 5.16, < 6.1.113`\n- `linux_kernel >= 6.2, < 6.6.55`\n- `linux_kernel >= 6.7, < 6.10.14`\n- `linux_kernel >= 6.11, < 6.11.3`\n- `sinec_os < 3.2`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.11.3`\n- `sinec_os 3.2`","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
