Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: hwmon: (axi-fan-control) Se corrigió la posible desreferencia del puntero NULL. Se podría llamar a axi_fan_control_irq_handler(), dependiente de la estructura privada axi_fan_control_data, antes de que se registre el dispositivo hwmon. Esto provocará el error "No se puede manejar la desreferencia del puntero NULL del kernel".
