Typically yes.  However, see below.

: the vulnerability has *always* been corrected in -current?

Standard operating proceedure is to commit to head, then to the
branches.

However, it is theoretically possible that a bug exists in current
that is exploitable in the same way that an advisory addresses.  I
think we've had this issue only once in the project's history.  The
code was in the kernel and the then-current -current was so different
from stable that patches to stable didn't fix the problem on current
and it took a while to realize that there was a problem and to fix
it.
