This highlights the critical risk of deploying security patches without adequate pre-release testing in representative environments, as even vendor-issued updates can introduce unintended operational disruptions. The fact that uninstalling the update restores functionality confirms the patch itself is the defect source, underscoring the need for rollback capabilities as part of standard patch management. Organizations that auto-deployed this update enterprise-wide with no staged rollout may have experienced widespread productivity loss before a fix or workaround was identified.",[53,54,55,56,57,58],"CIS Control 7: Continuous Vulnerability Management","CIS Control 7.4: Perform Automated Application Patch Management","NIST SP 800-40 Rev. 4: Guide to Enterprise Patch Management Planning","NIST SP 800-128: Configuration Management for Information Systems","ITIL Change Management: Standard and Emergency Change procedures","NIST IR 7788: Rollback and Recovery Planning for Software Updates",{}]
