Describes USMA, an approach to overcome limitations of gadget-based kernel attacks on Linux—particularly the difficulty of locating suitable gadgets and the constraints imposed by control-flow integrity mitigations like ARM PAC—by sharing or reusing kernel code to enable exploitation. Discusses techniques and tooling for finding or creating usable kernel code pieces to bypass those obstacles.
