CVE-2023-25769

Local denial of service via resource exhaustion

Published Feb 14, 2024 · Updated Aug 2, 2024

Uncontrolled resource consumption in Intel Thunderbolt DCH drivers for Windows before 88 allows local users to cause a service interrupt. Intel identifies the defect only as uncontrolled resource consumption and has not disclosed the affected driver component, resource, or triggering operation. Low-privileged authenticated local access is required, and the bounded reported consequence is denial of service with no confidentiality or integrity impact.
