CVE-2022-23287

Local privilege escalation through undisclosed ALPC flaw

Published Mar 9, 2022 · Updated Jul 8, 2025

Privilege escalation in affected Microsoft Windows releases allows local users with low privileges to gain higher privileges through ALPC. Microsoft identifies the affected component only as Windows ALPC and has not published the vulnerable routine, malformed operation, or input-handling error. Exploitation requires local low-privilege access and no user interaction; success compromises confidentiality, integrity, and availability at the elevated security context.
