CVE-2026-17463: CWE-400 Uncontrolled Resource Consumption in IBM Db2
IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.5 for Linux, UNIX and Windows (includes DB2 Connect Server) could allow a remote authenticated attacker to cause a denial of service due to uncontrolled resource consumption.
AI Analysis
Technical Summary
IBM Db2 versions 11.5.0 to 11.5.9 and 12.1.0 to 12.1.5 for Linux, UNIX, and Windows (including DB2 Connect Server) contain a CWE-400 uncontrolled resource consumption vulnerability. A remote attacker with authentication privileges can exploit this flaw to cause a denial of service condition by exhausting system resources. The CVSS 3.1 base score is 6.5, reflecting medium severity with network attack vector, low attack complexity, required privileges, no user interaction, and impact limited to availability.
Potential Impact
Successful exploitation results in denial of service, impacting the availability of the IBM Db2 service. There is no impact on confidentiality or integrity. This could disrupt database operations and affect dependent applications or services.
Mitigation Recommendations
Patch status is not confirmed from the provided information. No vendor advisory or patch links are included. Users should monitor IBM's official security advisories for updates and apply any official fixes once available. Until then, limit access to trusted authenticated users and monitor for unusual resource consumption patterns related to Db2.
