Once updates have been applied, any process using glibc will need to be restarted. Given that nearly all system processes use glibc, rebooting after upgrading is suggested.

IBM recommends that you review your entire environment to identify vulnerable releases of glibc including your Operating Systems and take appropriate mitigation and remediation actions. Please contact your Operating System provider for more information.
