Description of problem:
SELinux is preventing /usr/libexec/openssh/sshd-session from 'setattr' accesses on the file /(null).

*****  Plugin restorecon (94.8 confidence) suggests   ************************

If you want to fix the label. 
/(null) default label should be etc_runtime_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
Do
# /sbin/restorecon -v /(null)

*****  Plugin catchall_labels (5.21 confidence) suggests   *******************

If you want to allow sshd-session to have setattr access on the (null) file
Then you need to change the label on /(null)
Do
# semanage fcontext -a -t FILE_TYPE '/(null)'
where FILE_TYPE is one of the following: abrt_var_cache_t, auth_cache_t, auth_home_t, cgroup_memory_pressure_t, cgroup_t, faillog_t, gitosis_var_lib_t, gkeyringd_tmp_t, krb5_host_rcache_t, lastlog_t, mozilla_plugin_tmp_t, mozilla_plugin_tmpfs_t, openshift_tmp_t, pam_var_run_t, ssh_home_t, sshd_var_run_t, systemd_passwd_var_run_t, user_tmp_t, var_auth_t.
Then execute:
restorecon -v '/(null)'


*****  Plugin catchall (1.44 confidence) suggests   **************************

If you believe that sshd-session should be allowed setattr access on the (null) 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:
# ausearch -c 'sshd-session' --raw | audit2allow -M my-sshdsession
# semodule -X 300 -i my-sshdsession.pp
