untrusted pointer dereference

About this tag
The untrusted pointer dereference tag covers vulnerabilities in Windows and Microsoft Office where a program uses a pointer without verifying it points to valid memory, allowing attackers to escalate privileges or execute code. Recent discussions include CVE-2025-53801 in the Windows Desktop Window Manager (DWM) Core Library, which lets a local user elevate privileges; CVE-2025-54905 in Microsoft Office/Word, involving information disclosure or local execution; and CVE-2025-50165 in the Windows Graphics Component, a remote code execution flaw. These threads focus on understanding the technical details, verifying CVEs, and applying patches or mitigations. The tag is relevant for security researchers, IT administrators, and anyone tracking Microsoft security updates.
