CVE-2026-15824: IBM DataPower Gateway Denial of Service

Q: Which deployments are exposed to this issue?

IBM DataPower Gateway versions 10.5.0.0 through 10.5.0.22, 10.6.0.0 through 10.6.0.10, 10.6.1 through 10.6.6, and 11.0.0.0 through 11.0.0.2 are affected.

Q: Does exploiting this issue require authentication or user interaction?

No. The supplied severity vector indicates network-based exploitation with low attack complexity, no privileges required, and no user interaction required.

Q: What is the expected impact if exploitation succeeds?

The documented impact is denial of service caused by a heap-based buffer overflow. The severity vector also indicates low confidentiality impact, no integrity impact, and high availability impact.
