DescriptionCVE.org
Use after free in Windows DWM Core Library allows an authorized attacker to elevate privileges locally.
Executive ViewAI
A high-severity privilege escalation vulnerability in Windows DWM Core Library could allow authorized users to gain elevated system access. With no patch currently available, any Windows system running affected DWM components faces elevated risk until Microsoft releases a fix.
Implement application whitelisting to restrict execution of suspicious processes; enforce principle of least privilege and disable unnecessary user account privileges; enable Windows Defender Application Guard on critical systems; increase logging and monitoring of privilege escalation attempts; restrict physical and remote access to vulnerable systems; segment networks to prevent lateral movement from compromised accounts.

Attack Technique
Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
