Authenticated service interruption via unbounded resource allocation
Published Aug 12, 2025 · Updated Feb 13, 2026
Resource exhaustion in Windows DirectX allows remote authenticated users to interrupt service by triggering unbounded allocations. Microsoft identifies unchecked resource allocation in DirectX but has not disclosed the request type, resource, or function that fails to enforce limits or throttling. Exploitation requires low privileges and network reachability, needs no user interaction, and affects availability without reported data disclosure or modification.

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.
