 ell-guarded fortress that holds a treasure – an\n   unlimited god mode. 
 We hopped over the walls\, fooled the guards\, and\n   entered the holy gr
 ail of privileges. An attacker running in System\n   Management Mode (SMM)
  can bypass practically any security mechanism\,\n   steal sensitive infor
 mation\, install a bootkit\, or even brick the\n   entire platform. We dis
 covered a family of industry wide TOCTOU\n   vulnerabilities in various UE
 FI implementations affecting more than 8\n   major vendors making billions
  of devices vulnerable to our attack.\n   RingHopper leverages peripheral 
 devices that exist on every platform\n   to perform a confused deputy atta
 ck. With RingHopper we hop from ring\n   3 (user-space) into ring -2 (SMM)
 \, bypass all mitigations\, and gain\n   arbitrary code execution. In our 
 talk\, we will deep-dive into this\n   class of vulnerabilities\, exploita
 tion method and how it can be\n   prevented. Finally\, we will demonstrate
  a PoC of a full exploitation\n   using RingHopper\, hopping from user-spa
 ce into SMM.\n   '\n\n   1. https://defcon.outel.org/consolidated_page.htm
