Please try these patches which are in the queue:

https://patchwork.kernel.org/project/linux-crypto/patch/adCAFOgQ0y_I7SC7@gondor.apana.org.au/
https://patchwork.kernel.org/project/linux-crypto/patch/adBbht8ERe0z-z3B@gondor.apana.org.au/

Both fix pre-existing bugs that were uncovered by the aformentioned
change and syzbot.

Thanks,
