Summary
In the Linux kernel, the following vulnerability has been resolved: drm/connector: only call HDMI audio helper plugged cb if non-null On driver remove, sound/soc/codecs/hdmi-codec.c calls the plugged_cb with NULL as the callback function and codec_dev, as seen in its hdmi_remove function. The HDMI audio helper then happily tries calling said null function pointer, and produces an Oops as a result. Fix this by only executing the callback if fn is non-null. This means the .plugged_cb and .plugged_cb_dev members still get appropriately cleared.

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/connector: solo se llama al auxiliar de audio HDMI plugged cb si no es nulo. Al eliminar el controlador, sound/soc/codecs/hdmi-codec.c llama a plugged_cb con NULL como funci\u00f3n de devoluci\u00f3n de llamada y codec_dev, como se observa en su funci\u00f3n hdmi_remove. El auxiliar de audio HDMI intenta entonces llamar a dicho puntero de funci\u00f3n nulo, pero produce un error. Para solucionar esto, ejecute la devoluci\u00f3n de llamada solo si fn no es nulo. Esto significa que los miembros .plugged_cb y .plugged_cb_dev se borran correctamente."
