AI Analysis
Technical Summary
This vulnerability involves a concurrent execution issue using a shared resource without proper synchronization in the UI Automation Manager (uiamanager.dll) on Windows 11 version 23H2. An authorized attacker with local access can exploit this race condition to elevate their privileges on the affected system.
