When SELinux is disabled, SELinux policy is not loaded at all; it is not enforced and AVC messages are not logged. Therefore, all benefits of running SELinux listed in xref:{context}-benefits-of-selinux[Benefits of SELinux] are lost.
It is recommended to use permissive mode instead of permanently disabling SELinux. See xref:{context}-changing-to-permissive-mode[] for more information about permissive mode.
Disabling SELinux using the SELINUX=disabled option in the /etc/selinux/config results in a process in which the kernel boots with SELinux enabled and switches to disabled mode later in the boot process. Because memory leaks and race conditions causing kernel panics can occur, prefer disabling SELinux by adding the selinux=0 parameter to the kernel command line as described in Changing SELinux modes at boot time if your scenario really requires to completely disable SELinux.
