heap grooming

About this tag
Heap grooming is a memory manipulation technique often used in privilege escalation exploits targeting Windows systems. On WindowsForum.com, discussions cover vulnerabilities like CVE-2025-53801 in the Desktop Window Manager (DWM) Core Library, where heap grooming can be used to exploit an untrusted pointer dereference for local privilege escalation. Similarly, heap grooming is relevant to use-after-free bugs in the Windows kernel (CVE-2025-53151) and the Kernel Transaction Manager (CVE-2025-53140), enabling attackers to elevate privileges. These threads highlight how heap grooming helps arrange memory to achieve code execution in privileged processes, making it a critical concept for security researchers and IT administrators focused on Windows patch management and exploit mitigation.
