It is not a virus, it is a vulnerability in the kernel. This does not have an exploit coded for it yet, I haven't even (personally) seen a Proof of Concept.
Essentially, this problem can allow a local user to gain superuser (root) privledges. If you do not give access to untrusted users (SSH, telnet, etc) then this is not something you have to be worried about.
Mandrake will no doubt assist you in patching (or securing) this kernel, however the Mandrake distro handles this sort of thing.
