Add /lib/modules/*/modules.dep.  If that file is world writable you
have a local root exploit.  Due to the kernel bug, this has occurred on
Slackware installs.  As part of that exploit, people reported that
/var/log/wtmp and /var/run/utmp are also created with the wrong mask.
Not exploitable AFAIK but you can hide tasks if utmp is world writable.
