Session Abstract

  • Riscure (Martijn B) has created a fuzzer tool for OP-TEE. It has been successfully used to find a couple of potential security issues in OP-TEE.
  • As of today the tool is quite invasive in terms of making changes to the current OP-TEE source code.
  • In this session we would like to discuss whether there is anything we can do make the fuzzer code closer to upstream.
