Description of problem:
SELinux is preventing kexec from 'read' accesses on the file vmlinuz-4.3.4-300.fc23.x86_64.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
vmlinuz-4.3.4-300.fc23.x86_64 default label should be boot_t.
Then you can run restorecon.
# /sbin/restorecon -v vmlinuz-4.3.4-300.fc23.x86_64

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that kexec should be allowed read access on the vmlinuz-4.3.4-300.fc23.x86_64 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 kexec /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
