Memory disclosure and corruption
Published Oct 15, 2026 · Updated Oct 15, 2026
Memory bounds errors in HPE NonStop EXPAND T9057L02^AIG and earlier allow attackers to read and write memory via adjacent-network access. The public CNA record does not identify the affected function, triggering input, or incorrect bounds operation, and the referenced vendor bulletin was not readable during research. Exploitation requires adjacent-network access but no credentials or user interaction; the available evidence does not establish code execution or a specific service-failure mode.

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.
