Do we have a reproducer?
Please refer to this section of the referenced doc: https://github.com/google/syzkaller/blob/master/docs/syzbot.md#no-reproducer-at-all
In this case we don't even know what program from the log triggered it, because the crash happened in the background thread. Probably one of the programs doing openat$ptmx. And we only got 30 of such crashes overall, so it seems to be notoriously difficult to reproduce.
