Hmm. Sounds very possible. It matches the commit syzbot bisected to,
and looking at the reports, the I can't find anything that is 5.3 or

I did find a 5.3.0-rc2+ report, but that's still consistent with that
commit: it got merged just before 5.3-rc4.

So I think you're right.

I forget what the magic email rule was to report that something is
fixed to syzbot..
