Sensitive-data disclosure through observable timing differences
Published Jul 11, 2022 · Updated Sep 16, 2024
Observable timing discrepancy in Dell BSAFE Crypto-C Micro Edition before 4.1.5 allows physically proximate attackers to disclose sensitive data. Dell identifies only the weakness class and does not disclose the affected cryptographic operation or timing-dependent processing error. Exploitation requires physical access, low privileges, and high complexity; the disclosed impact is limited to confidentiality.
Summary

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.
