Saint Jude LKM is a Linux Kernel Module for 2.2.11 and greater kernels. This module implements the Saint Jude model for improper privilege transitions. This will permit the discovery of local, and ultimately, remote root exploits during the exploit itself. Once discovered, Saint Jude will terminate the execution, preventing the root exploit from occuring. This is done without checking for attack signatures of known exploits, and thus should work for both known and unknown exploits.
