CVE-2020-35168

Local information disclosure via timing discrepancy

Published Jul 11, 2022 · Updated Sep 16, 2024

Observable timing discrepancy in Dell BSAFE Crypto-C Micro Edition before 4.1.5 allows local users to infer sensitive data through timing observations. Dell has not published the affected cryptographic operation, the measured input-dependent timing behavior, or the specific data exposed. Exploitation requires low privileges, local execution, and high-complexity timing analysis; the published impact is confidentiality only.
