En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:
net: dsa: mt7530: corrige la desreferencia de NULL al desvincular MT7531 y MT7621
Las alimentaciones core e io solo se solicitan para ID_MT7530: tanto el devm_regulator_get() en la sonda como el regulator_enable() en mt7530_setup() están condicionados por el identificador del conmutador, pero mt7530_remove() las desactiva incondicionalmente. En un MT7621 o un MT7531 ambos punteros siguen siendo NULL desde devm_kzalloc(), así que rmmod o una desvinculación mediante sysfs llama a regulator_disable() sobre NULL.
