CVE-2024-43830

  2. Vulnerabilities (CVE)
  3. CVE-2024-43830
In the Linux kernel, the following vulnerability has been resolved: leds: trigger: Unregister sysfs attributes before calling deactivate() Triggers which have trigger specific sysfs attributes typically store related data in trigger-data allocated by the activate() callback and freed by the deactivate() callback. Calling device_remove_groups() after calling deactivate() leaves a window where the sysfs attributes show/store functions could be called after deactivation and then operate on the just freed trigger-data. Move the device_remove_groups() call to before deactivate() to close this race window. This also makes the deactivation path properly do things in reverse order of the activation path which calls the activate() callback before calling device_add_groups().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: leds: trigger: Anular el registro de los atributos sysfs antes de llamar a desactivar() Los activadores que tienen atributos sysfs específicos del activador normalmente almacenan datos relacionados en datos de activación asignados por la devolución de llamada enable() y liberados por el desactivar() devolución de llamada. Llamar a device_remove_groups() después de llamar a deactivate() deja una ventana donde los atributos sysfs muestran/almacenan funciones que se pueden llamar después de la desactivación y luego operar con los datos de activación recién liberados. Mueva la llamada device_remove_groups() antes de desactivar() para cerrar esta ventana de ejecución. Esto también hace que la ruta de desactivación haga las cosas correctamente en orden inverso a la ruta de activación que llama a la devolución de llamada enable() antes de llamar a device_add_groups().
