Local privilege escalation via improper input validation
Published Sep 10, 2024 · Updated Aug 10, 2026
Improper input validation in the Microsoft Windows Kernel Streaming Service Driver allows local users to elevate privileges. Microsoft has not disclosed the input, code path, or validation operation that fails inside the driver. Exploitation requires existing low-privileged access to an affected Windows host and can compromise confidentiality, integrity, and availability under the same security authority.
