Physical service interruption via unchecked return value
Published Feb 14, 2024 · Updated Aug 7, 2024
Unchecked return value in Intel Thunderbolt DCH drivers for Windows before 88 allows physically proximate attackers to interrupt service. The driver fails to check an unspecified operation's return value, but Intel has not disclosed the affected function, error path, or triggering input. Exploitation requires physical access to a Windows system with an affected Thunderbolt driver, and the published impact is limited to partial availability loss.
