Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: común: usb-conn-gpio: corrige la desreferencia del puntero NULL del cargador. Cuando se enciende el sistema con un cable OTG, la interrupción de IDDIG surge antes del registro del cargador, lo que provocará un puntero NULL desreferencia, solucione el problema registrando la fuente de alimentación antes de solicitar IDDIG/VBUS irq.
