CVE-2025-14688Network attack vector

Authenticated service interruption via undisclosed table fetch flaw

Published Apr 30, 2026 · Updated Apr 30, 2026

Denial of service in IBM Db2 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3 allows remote authenticated users to interrupt service. IBM has not disclosed the affected table-fetching code, the untrusted value it mishandles, or whether the interruption is a hang or crash. Exposure requires DB2_EXTENDED_OPTIMIZATION=NLJN_OFLOW ON together with DB2_WORKLOAD=ANALYTICS or intra_parallel=YES; the reported impact is limited to availability.
