There's still a symlink race condition. If at first the symlink points to /dev/something-legit or /media/something-legit, the symlink can be swapped easily by hooking into inotify's IN_ACCESS and changing what it points to just in time for mount to be called with the s ymlink pointing someplace naughty. An example of the technique is presented here: http://www.exploit-db.com/exploits/17932/ .

So, the vulnerability still stands.
