While attempting to build the module on a newer kernel I hit build error:
ERROR: modpost: "kallsyms_lookup_name" [src/afl_snapshot.ko] undefined!
Turns out recent patches to the kernel have unexported the kallsyms_lookup_name symbol so it can't be easily used in out-of-tree builds [1][2]. It's possible I might have missed something in my setup though.
