>SELinux is preventing /usr/bin/dmesg from 'read' accesses on the chr_file kmsg.
>
>*****  Plugin catchall (100. confidence) suggests  ***************************
>
>If you believe that dmesg should be allowed read access on the kmsg 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 dmesg /var/log/audit/audit.log | audit2allow -M mypol
># semodule -i mypol.pp
>
