CVE-2024-54178Network attack vector

Authenticated service interruption via unbounded database creation

Published Jun 22, 2026 · Updated Jun 22, 2026

Resource exhaustion in IBM Db2 on Cloud Pak for Data 4.8 through 5.3 allows remote authenticated users to interrupt database service. The Db2U database-creation path allocates resources without limits or throttling for each new database; IBM has not disclosed the specific resource or function involved. Authenticated access capable of creating databases is required, and successful exploitation affects availability without reported data disclosure or modification; Db2 Warehouse on Cloud Pak for Data is also affected.
