Which isn't very strange since:
[ 429.920201] Insufficient stack space to handle exception!
the system ran out of stack. With VMAP stack and IRQSTACKS there is really not much more memory we can provide.
When I discussed this with syzbot it seemed they were using some really big userspace program written in Go that just used up all the virtual memory :P
I don't know the nature of this test though. Using a lot of memory??
