Just a small nitpick...

Can you please drop the "- exploit attempt" from the error? Buffer
overflows aren't always exploits.



this message will only trigger if the kernel tries to _execute_ an
non-executable kernel page - which almost never happens even considering
kernel crashes. Normal kernel oopses will still look like they used to.


Perhaps the message should read like so:

kernel tried to execute NX-protected page - exploit attempt? (uid: 500)
Unable to handle kernel paging request at virtual address f78d0f40
