Normal patch window

BlackTree recommends the normal approved patch window. No accepted exploitation or emergency signal currently justifies an out-of-band change by itself.

BlackTree urgency is an operational review window. It does not replace vendor severity or CVSS.

Environment override questions

  • Is Microsoft SQL Server 2022 for x64-based Systems (CU 25) exposed to untrusted networks or content?
  • Does this update affect an identity, management, backup or other control-plane system?
  • Are compensating controls tested and monitored until the selected patch window?

Deployment context

Effects and caveats

  • Use the vendor update channel or update catalogue entry for the applicable product release.
