CVE-2025-39696

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: tas2781: Fix wrong reference of tasdevice_priv During the conversion to unify the calibration data management, the reference to tasdevice_priv was wrongly set to h->hda_priv instead of h->priv. This resulted in memory corruption and crashes eventually. Unfortunately it's a void pointer, hence the compiler couldn't know that it's wrong.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: ALSA: hda: tas2781: Corrección de referencia incorrecta de tasdevice_priv Durante la conversión para unificar la gestión de datos de calibración, la referencia a tasdevice_priv fue establecida incorrectamente a h->hda_priv en lugar de h->priv. Esto resultó en corrupción de memoria y bloqueos eventualmente. Desafortunadamente, es un puntero void, por lo tanto, el compilador no pudo saber que era incorrecto.
