Description of problem:
Trying to create a Fedora 23 install media using dd:
$ sudo dd if=Fedora-Live-Workstation-x86_64-23-10.iso of=/dev/sdb

SELinux is preventing abrt-hook-ccpp from 'open' accesses on the file /usr/lib/systemd/systemd-udevd.

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

If você acredita que o abrt-hook-ccpp deva ser permitido acesso de open em systemd-udevd file  por default.
Then você precisa reportar este como um erro.
Você pode gerar um módulo de política local para permitir este acesso.
Do
permitir este acesso agora executando:
# grep abrt-hook-ccpp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
