:SELinux is preventing /opt/google/chrome/chrome from read, append access on the file /dev/shm/.com.google.Chrome.8gCYFm (deleted).
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that chrome should be allowed read append access on the .com.google.Chrome.8gCYFm (deleted) 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 Chrome_ChildIOT /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
