you are running a very old kernel, and you are using at least one binary
only module... I don't think linux-kernel is the right forum for such an
issue ;)

Well sorry for not making me clear, i forgot to say that
im not using 2.4.20 or any other default kernel. Im using
2.6.10 from kernel.org.

the "vulnerability" im talking about is the following:

Try running a 2.6-ac kernel (the one that fixes this vulnerability is
2.6.10-ac9). The patch from 2.6.10 to 2.6.10-ac9 is linked on the
kernel.org web site. Here's the URL anyway:
