I got a mail that you converted it to private and I was like "that's weird", but then I realized there's a CVE attached, which I hadn't put together.

... Severity 8.9??  Nuh-uh.  Yes, it causes a crash, but the crash is to the *per-client* sshd instance.  It has no effect whatsoever on the overall system.  Unless someone has found an *exploit* based on this, it feels pretty low severity to me.

Neither here nor there, just commenting.

Side comment: for my first attempt at a fix I tried to use the 9.0p1 SRPM plus the 9.2p1 upstream source to make a package.

I now have *deep* respect for the Fedora maintainers of the openssh package.  OMG *so many* patches.  ;_;  Wish you could upstream them, but amazing that you deal with all that!
