Local data disclosure via timing discrepancy
Published Jul 11, 2022 · Updated Sep 17, 2024
Observable timing discrepancy in Dell BSAFE SDKs before Crypto-C Micro Edition 4.1.5 and Micro Edition Suite 4.6 allows data disclosure. Dell has not disclosed the affected cryptographic operation, the attacker-controlled inputs, or why their processing time differs. Exploitation requires local access and high-complexity timing observations, and the published consequence is limited to confidentiality.

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.
