June 2025 Patch Tuesday: what Security and IT teams should prioritise

The operational queue contains 88 approved patch records linked to 349 unique CVEs. BlackTree currently marks 17 records for an accelerated or out-of-band assessment. BlackTree urgency is separate from vendor severity, CVSS and EPSS.

Security teams should start with confirmed exploitation and exposed control-plane systems. IT administrators should then review applicability, prerequisites, restart impact, sequencing, known issues and rollback guidance on each patch detail page.
