Description of problem:
SELinux is preventing /usr/bin/kmod from 'write' accesses on the file /tmp/ffi87eUX8 (deleted).

*****  Plugin leaks (86.2 confidence) suggests  ******************************

If you want to ignore kmod trying to write access the ffi87eUX8 (deleted) 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/bin/kmod /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests  ***************************

If you believe that kmod should be allowed write access on the ffi87eUX8 (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 modprobe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
