Comment 1 Huzaifa S. Sidhpurwala 2020-03-27 06:37:30 UTC
Analysis:

This issue is only triggered with WPS pin needs to be generated and there is no /dev/urandom device. Such a scenario should not be possible in a typical server configuration, and may be a case in case of IoT or embedded devices. Therefore marking Red Hat Products as not affected.
