CWE

KEV

CWE ID	Description
CWE-843	The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
CWE-122	A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

Attack-Flow Graph

Executive Summary

This is a type confusion vulnerability in the Windows Desktop Window Manager (DWM) Core Library. It occurs when the system incorrectly handles data types, allowing an attacker with local access to escalate their privileges on the system.

Detection Guidance

This vulnerability involves a type confusion flaw in the Windows DWM Core Library that allows local privilege escalation. Detection typically requires analyzing system logs for unusual activity or crashes in the DWM process. Microsoft may provide specific detection guidance in their security updates or advisories.

Impact Analysis

An attacker could exploit this to gain higher-level permissions on your system, potentially allowing them to install programs, view or delete data, or create new accounts with full user rights.

Compliance Impact

This vulnerability allows local privilege escalation through type confusion in the Windows DWM Core Library. While it does not directly impact data protection or privacy controls, unauthorized privilege escalation could lead to unauthorized access to sensitive data, potentially violating compliance requirements under GDPR, HIPAA, or other standards that mandate strict access controls and auditability.

Mitigation Strategies

Apply the latest security updates from Microsoft to patch the Windows DWM Core Library vulnerability. Monitor Microsoft's official update guide for patches and install them promptly.
