The build ID parser checked ELF note sizes with uint32 additions, so an overflowing descriptor length could pass validation and panic while slicing the note. Parse and align sizes in uint64, check note bounds before advancing, and add a malformed ELF regression.
Review update: the unrelated generic-instantiation change and its fixture were removed through a normal follow-up commit; #1764 tracks that fix separately. Current-head validation: go test ./go/buildid -run TestReadELFRejectsOverflowingNoteSize (one test) passed; git diff --check passed. Prior validation text above is historical unless repeated here.
