Local privilege escalation through undisclosed graphics-kernel flaw
Published Oct 13, 2021 · Updated Aug 4, 2024
Elevation of privilege in the DirectX Graphics Kernel in affected Microsoft Windows releases allows local users to gain elevated privileges. Microsoft's public record identifies the kernel graphics subsystem but does not disclose the flawed operation or attacker-controlled input. Exploitation requires existing low-privilege local access and can compromise confidentiality, integrity, and availability within the existing security scope.
