Description of problem:
SELinux is preventing dbus-daemon from read, write access on the сокет socket.

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

If if you believe that dbus-daemon should be allowed read write access on the socket socket by default.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
allow this access for now by executing:
# ausearch -c 'dbus-daemon' --raw | audit2allow -M my-dbusdaemon
# semodule -X 300 -i my-dbusdaemon.pp
