  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nrapidio: fix an API misues when rio_add_net() fails\n\nrio_add_net() calls device_register() and fails when device_register()\nfails.  Thus, put_device() should be used rather than kfree().  Add\n\"mport->net = NULL;\" to avoid a use after free issue.",
