About this tag
The DirectX Graphics Kernel (dxgkrnl.sys) is a kernel-mode component in Windows that manages GPU scheduling, surface lifetimes, and driver stack interactions. Recent discussions on WindowsForum.com focus on security vulnerabilities in this subsystem, including elevation of privilege (EoP), denial of service (DoS), use-after-free, and race condition flaws. Multiple CVEs such as CVE-2026-20836, CVE-2026-20814, CVE-2025-60723, CVE-2025-60716, CVE-2025-55698, CVE-2025-55678, and CVE-2025-50172 have been addressed in Microsoft Patch Tuesday updates. These issues typically allow authenticated local or low-privilege attackers to crash systems or gain SYSTEM privileges. Administrators are advised to apply vendor patches promptly and verify KB-to-SKU mappings for affected Windows versions.
