This openssh bug was fixed in 8.8 per the release notes; indeed the fix[1] (which was misapplied but fixed next commit) looks familiar and it is just a straight up crasher, hence unlikely to cause other issues. Agree with you though that with both git and openssh getting changes released for this feature there is a probability that there might be misbehaving combinations that are not appropriately tested, but your patch is a good step in the right direction.
