Executive Summary

CVE-2026-3676 is a vulnerability in IBM Db2 for Linux, UNIX, and Windows (including DB2 Connect Server) and IBM Cloud APM products. It allows an authenticated user to cause a denial of service due to improper neutralization of special elements in the data query logic within the Fenced environment.

This means that the system does not properly handle certain special inputs in database queries, which can be exploited to disrupt the normal operation of the database server.

Impact Analysis

The vulnerability can be exploited by an authenticated user to cause a denial of service (DoS) on the affected IBM Db2 and IBM Cloud APM systems.

A denial of service means that legitimate users may be unable to access or use the database services, potentially leading to downtime and disruption of business operations.

Mitigation Strategies

To mitigate this vulnerability, users should apply fixes to their DB2 V11.5 server.

Additionally, install the 8.1.4.0-IBM-APM-SERVER-IF0004 or later server patch for the IBM Cloud Application Performance Management product.
