      "value": "The security fix for CVE-2025-0728 in eclipse-threadx NetX Duo refactors error handling in the HTTP server PUT process to use a shared cleanup label, but this unified cleanup path unconditionally calls fx_file_close() even when the file was never successfully opened. Multiple error branches jump to the shared cleanup label before any file open operation has occurred, causing fx_file_close() to operate on an uninitialized file handle, leading to undefined behavior, double-close issues, or memory corruption."

      "value": "La corrección de seguridad para CVE-2025-0728 en eclipse-threadx NetX Duo refactoriza el manejo de errores en el proceso PUT del servidor HTTP para usar una etiqueta de limpieza compartida, pero esta ruta de limpieza unificada llama incondicionalmente a fx_file_close() incluso cuando el archivo nunca se abrió con éxito. Múltiples ramas de error saltan a la etiqueta de limpieza compartida antes de que se haya producido cualquier operación de apertura de archivo, lo que hace que fx_file_close() opere en un descriptor de archivo no inicializado, lo que lleva a un comportamiento indefinido, problemas de doble cierre o corrupción de memoria."
