:SELinux is preventing /usr/sbin/dnsmasq from 'read' accesses on the chr_file /dev/null.
:*****  Plugin restorecon (93.9 confidence) suggests  *************************
:If you want to fix the label. 
:/dev/null default label should be null_device_t.
:Then you can run restorecon.
:# /sbin/restorecon -v /dev/null
:*****  Plugin leaks (6.10 confidence) suggests  ******************************
:If you want to ignore dnsmasq trying to read access the null chr_file, because you believe it should not need this access.
:Then you should report this as a bug.  
:You can generate a local policy module to dontaudit this access.
:# grep /usr/sbin/dnsmasq /var/log/audit/audit.log | audit2allow -D -M mypol
:# semodule -i mypol.pp
:*****  Plugin catchall (1.43 confidence) suggests  ***************************
:If you believe that dnsmasq should be allowed read access on the null chr_file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep dnsmasq /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
