Service interruption via unbounded LDAP resource consumption
Published May 13, 2025 · Updated Feb 13, 2026
Uncontrolled resource consumption in Microsoft Windows LDAP allows remote attackers to interrupt service with crafted network traffic. Microsoft has not disclosed which LDAP request-processing locus consumes resources without an effective bound or cleanup path. No authentication or user interaction is required, but exploitation has high complexity and the reported consequence is limited to availability.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
