Technical details
A buffer over-read vulnerability exists in the Windows Overlay Filter driver. The vulnerability allows an authenticated local attacker to read beyond the bounds of an allocated buffer, enabling disclosure of adjacent memory contents. Exploitation requires local system access and user authentication; it cannot be exploited over the network. The flaw may expose sensitive kernel or application data, though code execution is not directly achievable through this vector alone. A patch is available from Microsoft.
