Local privilege escalation via CSRSS
Published Oct 10, 2023 · Updated Apr 14, 2025
Elevation of privilege in Microsoft Windows CSRSS on affected builds allows local users to gain SYSTEM privileges via a local attack. The published records do not disclose the vulnerable CSRSS operation or code path, so the mechanism remains undisclosed. Exploitation requires local user access and no user interaction; successful exploitation can grant system-level confidentiality, integrity, and availability impact.

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.
