Please note that the original email does have a reproducer and kernel config
attached, and specifies the exact git commit of the kernel version on which we
found this crash. I am happy to manually test any patch attempts. Unfortunately,
I do not have the infrastructure to host an automated system similar to syzbot.
Please let me know if there is any additional information in regards
to this report
that would be helpful for you!

As of right now, we are not yet ready to approach the team around syzkaller
to see if they are interested in our modifications as our work is still ongoing
research. We are certainly hoping to do this at a later stage!

Wishing you a nice start to the week!

Best,
Marius
