Authenticated denial of service via undisclosed access control

Published Feb 14, 2024 · Updated Aug 16, 2024

Improper access control in Intel Thunderbolt DCH drivers for Windows before version 88 allows local users to cause a denial of service. Intel has not disclosed the affected driver component, the protected operation, or how access control is applied incorrectly. A low-privilege authenticated Windows session is required, and the published impact is limited to interrupting service rather than reading or modifying data.
