Service interruption via uncontrolled cryptographic resource consumption
Published Apr 8, 2025 · Updated Aug 10, 2026
Uncontrolled resource consumption in Windows Cryptographic Services allows remote attackers to interrupt affected Windows systems over a network. Microsoft has not disclosed the specific cryptographic-service locus, input, or resource whose unchecked consumption exhausts the target. Exploitation requires no authentication or user interaction, and the published impact is limited to service availability.
