Summary
drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation

This commit addresses a potential index out of bounds issue in the cm3_helper_translate_curve_to_degamma_hw_format function in the DCN30 color management module. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFERFUNCPOINTS).

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.
