CVE-2026-10695 · Severity: medium · CVSS 6.2 · Published 2026-07-30

IBM Db2 is a database management system used to store and manage large volumes of corporate data. A vulnerability in its federated server component—which allows the database to access data from other sources—could allow an attacker to trigger a denial of service. If exploited, this could cause the database to crash or become unresponsive, disrupting business operations and data availability.

## Technical details

IBM Db2 is vulnerable to uncontrolled resource consumption (CWE-400) within the federated server component. The issue occurs specifically when running non-fenced federated queries, which execute in the same address space as the database engine. A local attacker can exploit this to trigger a denial of service condition, impacting system availability. IBM has released a fix in version 12.1.5 (Special Build #87349). As a workaround, administrators can set the federated wrapper to fenced mode using the 'ALTER WRAPPER' command to isolate the process.
