Data exposure via voltage or clock glitch
Published Sep 12, 2022 · Updated Sep 17, 2024
Fault-injection weakness in Dell Client Platform BIOS on pre-21Q4 platforms allows physically proximate attackers to expose data. Dell has not published the affected firmware locus or how a voltage or clock glitch causes the fault condition that changes system behavior. Exploitation requires physical access, high attack complexity, and specialized fault-injection equipment; the reported consequence is limited to confidentiality loss.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
