Description of problem:
SELinux is preventing /usr/libexec/mission-control-5 from read, write access on the chr_file /dev/tty2.

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

If you want to ignore mission-control-5 trying to read write access the tty2 chr_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/libexec/mission-control-5 /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

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

If you believe that mission-control-5 should be allowed read write access on the tty2 chr_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 mission-control /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
