CVE-2025-1493Network attack vector

Authenticated service interruption via shared-resource race

Published May 5, 2025 · Updated Aug 28, 2025

Race condition in IBM Db2 for Linux, UNIX, and Windows 12.1.0 through 12.1.1 allows remote authenticated users to cause a service interrupt. Concurrent execution accesses an undisclosed shared resource without adequate synchronization; IBM withholds the affected functionality and replication steps. Network access with valid Db2 credentials and a high-complexity race are required, and the documented consequence is limited to availability.
