SELinux is preventing /usr/sbin/userhelper from 'getattr' accesses on the chr_file /dev/vcsa1.

... and similar AVC denials are generated for all files in /dev/ when I start liveusb-creator.

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

If you believe that userhelper should be allowed getattr access on the vcsa1 chr_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 userhelper /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
