[Blog post](https://securitylab.github.com/research/stack-buffer-overflow-qualcomm-msm/) [Snapshot for this demo](https://github.com/github/securitylab/releases/download/qualcomm-msm-codeql-database/msm-4.4-revision-2017-May-07--08-33-56.zip) The blog post was written before we had the C++ dataflow library, so these demo queries are a bit different than the blog post.
