CVE-2020-35165

Local information disclosure via undisclosed timing discrepancy

Published May 22, 2024 · Updated Aug 4, 2024

Observable timing discrepancy in Dell BSAFE Crypto-C Micro Edition before 4.1.5 and Micro Edition Suite before 4.6 exposes data to local users. Dell has not published the affected cryptographic operation or explained which secret-dependent operation produces the timing difference. Exploitation requires local access, no prior privileges, and high-complexity timing measurements; the reported impact is confidentiality loss only.
