CVE-2026-6053: CWE-770 Allocation of Resources Without Limits or Throttling in IBM Db2
CVE-2026-6053 is a medium severity vulnerability in IBM Db2 versions 11. 5. 0 through 11. 5. 9 and 12. 1. 0 through 12. 1. 4. It involves allocation of resources without limits or throttling when processing specially crafted queries on range partitioned tables, leading to a denial of service condition.
AI Analysis
Technical Summary
IBM Db2 versions 11.5.0 to 11.5.9 and 12.1.0 to 12.1.4 contain a vulnerability classified as CWE-770 (Allocation of Resources Without Limits or Throttling). This flaw allows an attacker with limited privileges to run specially crafted queries against range partitioned tables, causing excessive resource consumption and resulting in denial of service. The CVSS 3.1 base score is 5.5, reflecting a medium severity with local attack vector, low complexity, and no user interaction required. The vulnerability affects availability only, with no impact on confidentiality or integrity. No patch or official remediation level has been published by IBM as of the current data.
Potential Impact
Successful exploitation leads to denial of service by exhausting resources during query processing on range partitioned tables. There is no impact on data confidentiality or integrity. The attack requires local access with low privileges and does not require user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the IBM advisory for current remediation guidance. Until an official fix is released, limit access to Db2 instances to trusted users and monitor for unusual query patterns involving range partitioned tables. No vendor-provided mitigation or workaround is currently documented.
