RSA information disclosure via timing side channel
Published Mar 11, 2025 · Updated Sep 1, 2025
Timing side channel in IBM CCA and 4769 Developers Toolkit 7.0.0 through 7.5.51 allows remote attackers to obtain sensitive RSA information. IBM states that certain RSA operations expose timing differences but has not identified the operation, code path, or secret-dependent step. Network access without authentication is sufficient, but exploitation requires high-complexity timing measurements and only discloses sensitive information.

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.
- Affected versionversion=7.0.0 <=7.5.51
