Apologies for the late reply. Yes this bug was reported by syzbot (https://syzkaller.appspot.com/bug?extid=921873345a95f4dae7e9) and I was able to reproduce it locally on my machine. I've just tested it with the latest upstream and confirmed that the bug is still present. I will send a revised patch shortly, please feel free to take a look. Chang
