CVE-2024-28885Network attack vector

Information disclosure via observable discrepancy

Published Nov 13, 2024 · Updated Nov 14, 2024

Observable discrepancy in Intel QAT Engine for OpenSSL before 1.6.1 allows remote attackers to disclose information over a network. Intel identifies CWE-203 but does not disclose the affected operation, the observable response or behavior, or the secret-derived input creating the discrepancy. Exploitation requires no privileges or user interaction but has high attack complexity, and the documented consequence is limited to confidentiality.
