I was really asking what RPM version.  Sorry.  Are you fully up to date 
on SELinux policy.

yum -y update selinux-policy-targeted

The command you executed is allowed in Rawhide.  And it should be 
allowed in F9.  It looks like the current F9 policy, mount_t is allowed 
to read all content. Including default_t, if you have the 
allow_mount_anyfile boolean set.
