Potential fix for https://github.com/rzr/z-wave-protocol-controller/security/code-scanning/19
To fix the issue, we need to validate the return value of
snprintfafter each call. If the return value is negative or exceeds the remaining buffer size, we should stop further writes to prevent buffer overflow. This involves:snprintfin a variable.sizeof(message) - index).Suggested fixes powered by Copilot Autofix. Review carefully before merging.
