n the Linux kernel, the following vulnerability has been resolved: drm/xe/nvm: Fix double-free on aux add failure After a successful auxiliary_device_init(), aux_dev->dev.release (xe_nvm_release_dev()) is responsible for the kfree(nvm). When there is failure with auxiliary_device_add(), driver will call auxiliary_device_uninit(), which call put_device(). So that the .release callback will be triggered to free the memory associated with the auxiliary_device. Move the kfree(nvm) into the auxiliary_device_init() failure path and remove the err goto path to fix below error.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: drm/xe/nvm: Corrige doble liberación en fallo de adición de aux Después de una exitosa auxiliary_device_init(), aux_dev-&gt;dev.release (xe_nvm_release_dev()) es responsable de la kfree(nvm). Cuando hay un fallo con auxiliary_device_add(), el controlador llamará a auxiliary_device_uninit(), que llama a put_device(). De modo que la devolución de llamada .release se activará para liberar la memoria asociada con el auxiliary_device. Mueve la kfree(nvm) a la ruta de fallo de auxiliary_device_init() y elimina la ruta err goto para corregir el error a continuación.
