Okay, the bug still exists in 4.13.0-21-generic, but went away in 4.13.0-25-generic once I removed 'apparmor=0'. So I think Tetsuo may be on to something.
Could this be a duplicate of this[0] bug? This would make sense considering the message of one the problematic commits is "add stacking support to apparmor network hooks". I'm not well versed enough in the kernel internals to say for sure, so I'm deferring to someone who knows better. Also, I'm not sure if I'm missing something, but while that bug is marked as "Fix Committed" in Launchpad[0], and a request was made to revert the pair of commits[1], I neither see a reply to that email saying the commits were indeed reverted nor subsequent commits to the Artful repo reverting the files affected by these commits. Is it possible that email got lost?
