CVE-2026-15819— IBM DataPower Gateway Out-of-bounds Write

Quick assessment

Affected
IBM DataPower Gateway 10.6CD
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

IBM DataPower Gateway 版本 10.5.0.0 至 10.5.0.22、10.6.1 至 10.6.6、10.6.0.0 至 10.6.0.10，以及 11.0.0.0 至 11.0.0.2 存在漏洞，远程攻击者可能利用排序比较器中因违反严格弱序（strict-weak-ordering）规则而导致的越界内存访问，从而引发拒绝服务（Denial of Service, DoS）攻击。
