Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pinctrl: aspeed: Se corrige la posible desreferenciación de NULL en aspeed_pinmux_set_mux() pdesc podría ser nulo, pero aún así desreferenciar pdesc->name y esto conducirá a un acceso a un puntero nulo. Por lo tanto, movemos una verificación de valores nulos antes de la desreferenciación.
