CVE-2026-15824

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 buffer overflow, with no public exploit references suggesting complex payload development may be needed.

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.
