Potential fix for https://github.com/flatcar/update_engine/security/code-scanning/3
To fix the issue, we need to avoid unsigned subtraction in the loop condition. Instead of
count - bytes_written > 0, we can directly comparebytes_writtenwithcountusingbytes_written < count. This approach avoids the risk of underflow and achieves the same logical result.The fix involves replacing the condition on line 21 with
bytes_written < count. This change ensures that the loop behaves correctly regardless of the values ofcountandbytes_written.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
