I think all this is already in TL since long:
	2024-01-21  Karl Berry  <karl at freefriends.org>

	* libttf/hdmx.c (ttfLoadHDMX): calloc the number of widths that we
	actually read, namely numGlyphs+1. I don't understand why this
	is numGlyphs+1 and not numGlyphs, per
	but since the program has always read numGlyphs+1, just leaving it.
	Report (and alternate fix) from attackoncs,

Best wishes
