CVE-2026-14509— IBM DataPower Gateway Denial of Service
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 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 版本中，由于链表遍历存在算法复杂度问题，可能导致远程攻击者引发拒绝服务（DoS）攻击。
