CVE-2022-50857 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: rapidio: rio: fix possible name leak in rio_register_mport() If device_register() returns error, the name allocated by dev_set_name() need be freed. It should use put_device() to give up the reference in the error path, so that the name can be freed in kobject_cleanup(), and list_del() is called to delete the port from rio_mports.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
