I think we can assume all branches are affected here [marking as such].

In my test VM, I was able to confirm the POC crashes Firefox Nightly builds as old as 2024-01-01 (version 123.0a1), plus a few newer builds as well, so I think we can assume esr128 and current release/beta are affected.

I haven't yet been able to test esr115 -- it won't launch in my VM for some reason -- but the patch applies cleanly to it, and the FontFaceSet::Load mechanics don't appear to have been touched very much for ages, so I think it's best to assume esr115 is also affected for now.
