In the Linux kernel, the following vulnerability has been resolved: pinctrl: devicetree: fix refcount leak in pinctrl_dt_to_map() If we fail to allocate propname buffer, we need to drop the reference count we just took. Because the pinctrl_dt_free_maps() includes the droping operation, here we call it directly.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: pinctrl: devicetree: corrige la fuga de recuento de referencia en pinctrl_dt_to_map() Si no asignamos el búfer de nombre de propiedad, debemos eliminar el recuento de referencias que acabamos de tomar. Debido a que pinctrl_dt_free_maps() incluye la operación de eliminación, aquí la llamamos directamente.
