Authenticated service interruption
Published Jul 8, 2025 · Updated Feb 13, 2026
Uncontrolled resource consumption in Windows Print Spooler Components allows remote authenticated users to interrupt service. Microsoft has not disclosed the specific spooler locus, attacker-controlled input, or resource operation responsible for exhaustion. Exploitation requires low privileges and adjacent-network reachability; the documented consequence is service interruption only.

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.
