FreeBSD 7.2 VFS/devfs race condition exploit 0day

FreeBSD 7.2 and below (including 6.4) are vulnerable to race condition in VFS
and devfs code, resulting in NULL pointer dereference. In contrast to pipe race
condition, this vulnerability is actually much harder to exploit.

It's not a 0-day. The bug was known and is fixed. It's a 0-day exploit when it abuses an unknown bug.
