Description of problem:
SELinux is preventing /usr/libexec/fprintd from 'read' accesses on the file /proc/<pid>/cmdline.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that fprintd should be allowed read access on the cmdline file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep fprintd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
