The present document aims to demonstrate a design weakness found in the
handling of simply 
linked   lists   used   to   register   binary   formats   handled   by
Linux   kernel,   and   affects   all   the   kernel 
families (2.0/2.2/2.4/2.6), allowing the insertion of infection modules
in kernel­ space that can be 
used by malicious users to create infection tools, for example rootkits.
