This repository hosts a book: Markdown sources, CSS, and a CI workflow. It does not ship executable CUDA kernels, and the code snippets are teaching material, not production libraries. Nonetheless, we take security reports seriously.

Do not open a public issue for security problems. Instead, report them privately by email to the repository owner (see the git author information in the repository) with the subject line [gpu-parallel-book] security report.

Please include:

1. A description of the issue and its impact.
2. The affected file and section (for content) or workflow (for CI).
3. A minimal reproduction, if applicable.

• Malicious or broken instructions in the book's code snippets that could cause data loss or system damage if followed literally.
• Compromised dependencies in the GitHub Actions workflow (actions/checkout, actions/configure-pages, etc.).
• Phishing or malicious links in the book or README.

• General CUDA programming mistakes (the book exists to teach these; report them as normal issues instead).
• Vulnerabilities in NVIDIA's CUDA toolkit, drivers, or libraries; report those to NVIDIA directly.

We will acknowledge receipt within 7 days and aim to resolve or triage the issue within 30 days. As this is a volunteer project, response times may vary.
