  "description": "In the Linux kernel, the following vulnerability has been resolved:  mISDN: fix possible memory leak in mISDN_dsp_element_register()  Afer commit 1fa5ae857bb1 (\u0022driver core: get rid of struct device\u0027s bus_id string array\u0022), the name of device is allocated dynamically, use put_device() to give up the reference, so that the name can be freed in kobject_cleanup() when the refcount is 0.  The \u0027entry\u0027 is going to be freed in mISDN_dsp_dev_release(), so the kfree() is removed. list_del() is called in mISDN_dsp_dev_release(), so it need be initialized.",
