Description of problem:

sealert -l 9864c067-b7e7-406e-8e7c-2bf895c667be
SELinux is preventing /usr/sbin/xtables-multi from 'read, write' accesses on the file .

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

If you want to ignore xtables-multi trying to read write access the  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.
Do
# grep /usr/sbin/xtables-multi /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

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

If you believe that xtables-multi should be allowed read write access on the  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 iptables /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Additional info:
Not sure if this is relevant, but I have applied the CIS recommendations (v1.0) for RHEL7. In particular, there is a suggestion of tmpfs being involved.

# mount | grep tmpfs
devtmpfs on /dev type devtmpfs (rw,nosuid,seclabel,size=498208k,nr_inodes=124552,mode=755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,seclabel)
tmpfs on /run type tmpfs (rw,nosuid,nodev,seclabel,mode=755)
tmpfs on /sys/fs/cgroup type tmpfs (rw,nosuid,nodev,noexec,seclabel,mode=755)
none on /run/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,seclabel)
