Indeed, I see that's a corner case, and maybe documentation could be improved. I guess I'm not the only one who didn't know about that. Even the common scenario of updates only touching userland is still kind of a FAQ on the forums, although this one is widely known (and IMHO documented well enough). > > > - FreeBSD-kernel with the version reported by > > > uname -k: > > > this is how it is currently documented.

I will sleep on this. I now have to agree there's just no *correct* way right now. So in a nutshell, the effect is that the vulnerability belongs to the kernel, but it's impossible to tell from the kernel version whether the patch is properly applied :( > Sorry for not replying earlier.

Actually glad it was the latter and there are things going on to improve on this, thanks again!
