CVE-2026-16176

Summary

IBM DataPower Gateway suffers from a memory reallocation vulnerability where improper validation of length fields can lead to heap-based buffer overflows during dynamic memory allocation, potentially causing denial of service conditions.

Exploitability

Exploitation appears difficult without additional vulnerabilities or specific input conditions, requiring precise control over memory allocation patterns and likely limited to remote attackers with network access to the DataPower gateway services.

Blast radius

If exploited, this vulnerability could disrupt critical API gateway and integration services, affecting multiple applications and users relying on DataPower's routing and transformation capabilities.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to IBM DataPower Gateway 10.5.0.23 or 10.6.7 or 11.0.3 to address this memory reallocation flaw.
