Noise. You can's accnounce every possibly security-related fix found
by an audit - note that it's not clear whether it actually _is_
security-relevant at this point and certainly no one wrote an exploit

It's not an exception. Fixes can and will change the ABI all the time.
You should not expect to be able to load a binary kernel module into
_any_ other one than the one it was compiled against. Sometimes
security fixes may even break the source API. (remember the dcache
issues in 2.2.<early>?).
