For context, while the input caused a crash with AFL (not fuzzing with ASAN) and it crashes with ASAN, I was unable to reproduce the crash with libass externally. I was only able to take up a hug amount of memory and take a long time to finish parsing the input.

I asked if they dev wanted to reject the CVE but got no strong response either way, so I decided to not pursue it.
