Con la disposici\u00f3n actual de bloqueo de la zona t\u00e9rmica en el c\u00f3digo debugfs, el espacio de usuario puede abrir el archivo de \"mitigaciones\" para una zona t\u00e9rmica antes. El puntero debugfs de la zona est\u00e1 configurado, lo que dar\u00e1 como resultado una desreferencia del puntero NULL en tze_seq_start().

Luego, puede borrar tz-&gt;debugfs despu\u00e9s de que una de esas funciones lo haya verificado y el objeto struct Thermal_debugfs puede liberarse prematuramente.
