      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: hda/cs_dsp_ctl: Use private_free for control cleanup\n\nUse the control private_free callback to free the associated data\nblock. This ensures that the memory won't leak, whatever way the\ncontrol gets destroyed.\n\nThe original implementation didn't actually remove the ALSA\ncontrols in hda_cs_dsp_control_remove(). It only freed the internal\ntracking structure. This meant it was possible to remove/unload the\namp driver while leaving its ALSA controls still present in the\nsoundcard. Obviously attempting to access them could cause segfaults\nor at least dereferencing stale pointers."

Use la devoluci\u00f3n de llamada de control private_free para liberar el bloque de datos asociado. Esto garantiza que la memoria no se pierda, sea cual sea la forma en que se destruya el control. La implementaci\u00f3n original en realidad no elimin\u00f3 los controles ALSA en hda_cs_dsp_control_remove(). S\u00f3lo liber\u00f3 la estructura de seguimiento interna. Esto significaba que era posible quitar/descargar el controlador del amplificador dejando sus controles ALSA todav\u00eda presentes en la tarjeta de sonido. Obviamente, intentar acceder a ellos podr\u00eda provocar errores de segmentaci\u00f3n o al menos eliminar la referencia a punteros obsoletos."
