CVE-2026-14496

Summary

A heap-based buffer overflow in IBM DataPower Gateway allows remote attackers to cause a denial of service by sending specially crafted input that exceeds allocated buffer boundaries, potentially leading to application crashes or unavailability.

Exploitability

Exploitation appears moderately difficult as it likely requires precise input crafting to trigger the heap overflow, though no public exploits are currently available and the vulnerability affects multiple versions without clear precondition requirements.

Blast radius

The impact could be significant in environments where DataPower gateways serve as critical API or proxy services, potentially causing widespread service disruption across applications relying on these gateways.

Detection

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

Prioritized remediation

Upgrade to IBM DataPower Gateway 10.5.0.23, 10.6.7, 10.6.0.11, or 11.0.0.3 to remediate this vulnerability.
