If you discover a security vulnerability in KVortex, please report it responsibly:

Please DO NOT open a public GitHub issue for security vulnerabilities.

Instead, contact us directly at:

• Email: contact@ayinedjimi-consultants.fr
• Subject: [SECURITY] KVortex Vulnerability Report

When reporting a vulnerability, please include:

1. Description: Clear description of the vulnerability
2. Impact: Potential impact and attack scenarios
3. Reproduction: Step-by-step instructions to reproduce
4. Environment: System details (OS, CUDA version, GPU model)
5. Suggested Fix: If you have one (optional)

• Initial Response: Within 48 hours
• Status Update: Within 7 days
• Fix Timeline: Depends on severity (Critical: 7-14 days, High: 30 days, Medium/Low: 60 days)

We appreciate responsible disclosure and will:

• Credit you in the security advisory (unless you prefer to remain anonymous)
• Keep you updated on the fix progress
• Notify you when the fix is released

When using KVortex in production:

1. Memory Safety

   • Always validate input sizes before allocations
   • Use provided error handling (std::expected)
   • Monitor memory usage with get_stats()

2. Thread Safety

   • KVortex is thread-safe by design
   • Follow API documentation for concurrent usage
   • Avoid mixing sync/async operations on same blocks

3. CUDA Security

   • Keep CUDA drivers updated
   • Use latest CUDA toolkit (13.1+)
   • Monitor GPU memory limits

4. Dependencies

   • Keep OpenSSL updated (3.0+)
   • Use latest stable GCC (13.3+)
   • Regularly update system libraries

5. Production Deployment

   • Enable all compiler warnings (-Wall -Wextra -Werror)
   • Run memory leak detection before deployment
   • Use sanitizers during testing (ASan, TSan, UBSan)
   • Monitor cache statistics for anomalies

• Large allocations may fail on systems with limited RAM
• Pinned memory is limited by system configuration
• Always check return values from create() and allocate()

• Uses OpenSSL's EVP API for cryptographic hashing
• Collision-resistant for cache indexing purposes
• Not designed for authentication or signing

• Cache index uses shared mutexes (read-heavy optimization)
• LRU eviction is protected by exclusive locks
• No deadlock scenarios in current implementation

Security updates will be released as:

• Patch versions (e.g., 1.0.1) for minor issues
• Minor versions (e.g., 1.1.0) for important fixes
• Security advisories on GitHub for critical issues
