Turns out I did not have the latest bios despite what Asus's wonderful
Windows autoupdate utility claimed. I manually downloaded and installed
the latest bios, which contains an Intel microcode update, and I haven't
had a single crash since.
I even had the intel-microcode package installed, but
I tried Fedora Rawhide (26's nouveau doesn't work with my graphics
card), with kernel 4.14.0-0.rc2.git4.1.fc28.x86_64, repeatedly starting
atom and chrome is the easiest way to trigger it.
I also tried security=none and disabling hyperthreading (even though I
should have the microcode fix for the

memtest.
This is with the 4.13 ubuntu kernel:
Just a comment from a security module developer.
What happens if you pass security=none to kernel command line options
(i.e. disable AppArmor security module), for I think it might help
isolating the problem because you are hitting oops at
security_vm_enough_memory_mm() and security_file_free().
Got an oops with 4.14 that hung firefox (like the ubuntu 4.13 kernel),
had to hard-reset because the restart process couldn't kill my session.
The 4.14-rc2 mainline kernel has some other bugs: network-manager can't

no other versions of the kernel in the repository.
I'm going to try the mainline kernels.

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.14
