Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability in the Windows Graphics Kernel. It allows an authorized attacker with local access to exploit memory corruption and elevate their privileges on the system.

Detection Guidance

Detection of this vulnerability typically requires monitoring for unusual system behavior or crashes related to the Windows Graphics Kernel. Microsoft may provide detection guidance in security updates or advisories. Check the Microsoft Update Guide for CVE-2026-102194 for official tools or commands.

Impact Analysis

An attacker could gain higher privileges on your system, allowing them to install programs, view or delete data, or create new accounts with full user rights. This requires local access but could lead to significant system compromise.

Compliance Impact

This vulnerability allows local privilege escalation in Windows systems, which could enable unauthorized access to sensitive data or system functions. For GDPR, this may increase risks of unauthorized data access or processing, potentially violating confidentiality requirements. Under HIPAA, local privilege escalation could lead to unauthorized access to protected health information, compromising security controls.

Mitigation Strategies

Apply the latest Windows security updates from Microsoft to patch the Graphics Kernel vulnerability. Monitor Microsoft's security advisories for updates and ensure all affected Windows versions are updated.
