Goals

  • Find out more exploitable regions inside the libtriton.so library.

What I worked on

  • The extractor and injector and finally complete and I was able to find few exploitable flips in both the fused attention kernel and the matmul kernel.
  • multipass won’t be the best environment for kernel-dev, I will have to look for other solutions.

Key Insights

  • In the current implementation of the injector when the --filter-by-ptx is enabled it misses a few opcodes like div.full.
