CVE-2024-33617Network attack vector

Information disclosure via RSA control-flow leakage

Published Nov 13, 2024 · Updated Nov 14, 2024

Insufficient control flow management in Intel QAT Engine for OpenSSL before 1.6.1 allows remote attackers to disclose data via network access. The RSA acceleration paths use secret-dependent control flow during private-key operations rather than constant-time selection. Exploitation requires a network-reachable application using an affected RSA path plus additional attack conditions; no integrity or availability impact is reported.
