About this tag
The local eop tag covers elevation-of-privilege vulnerabilities in Microsoft Windows components, including Win32K GRFX, Brokering File System, Defender Firewall Service, PC Manager, Push Notifications, WinSock AFD, and DirectX Graphics Kernel. Common root causes are race conditions and type confusion. These flaws allow an authenticated local user to escalate to SYSTEM-level access. Discussions focus on patch guidance, detection, and mitigation for enterprise IT environments. The tag is relevant for sysadmins and security researchers tracking Windows local privilege escalation threats.
