CVE-2023-24463

Adjacent information disclosure

Published Feb 14, 2024 · Updated Aug 2, 2024

Improper input validation in Intel Thunderbolt DCH drivers for Windows before version 88 allows attackers to disclose data via adjacent access. Intel has not published the affected validation locus, the accepted malformed input, or the driver operation that exposes data. Exploitation requires adjacency to a system with an affected driver and exposes confidentiality only; no integrity or availability impact is reported.
