The corrupted pte message means the pte unexpectedly points outside the range
of the regular mem_map. There is not too much I can gather from the crash:

The calltrace is pretty jumbled, but even if it was accurate, the it is only
the path via which the corruption is detected, not where it occurred.

vm_flags is
It could be a library or program text mapping, I suppose (we don't print out
vm_file or vm_ops information in these messages, so it is hard to know).

is not surprising -- just a regular user page. The corruption is likely to be
the higher order bits of the pte.

It's almost impossible to make any useful progress on this unless you we can
reproduce it. If you can reliably reproduce, we could eventually narrow it
Although I do think it might be an overheating issue: it is very common to see
the kernel hit memory corruption in pages and pagetables...
