CVE-2026-16167

Summary

IBM DataPower Gateway suffers from a buffer overflow vulnerability due to improper bounds checking, allowing remote attackers to cause a denial of service by sending specially crafted requests that exceed allocated memory boundaries.

Exploitability

Exploitation appears moderately difficult as it requires crafting specific malformed requests that trigger the bounds checking failure, with no public exploit references suggesting attackers must develop custom payloads.

Blast radius

The impact could be significant across organizations using DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2, potentially causing widespread service disruption.

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.
