CVE-2025-0915
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM Db2 for Linux, UNIX and Windows (includes DB2 Connect Server) 11.5.0 through 11.5.9 and 12.1.0 through 12.1.1 under specific configurations could allow an authenticated user to cause a denial of service due to insufficient release of allocated memory resources.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIBM Db2 versions 11.5.0-11.5.9 and 12.1.0-12.1.1 contain a memory leak vulnerability where authenticated users can trigger insufficient release of allocated memory resources under specific configurations, leading to denial of service through memory exhaustion.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Db2 version is within affected rangeRun 'db2level' command or query 'SELECT GET_VARCHAR_FOR_BIT_DATA(SYSPRODINFO.PROD_RELEASE) AS VERSION FROM SYSIBM.SYSPRODINFO' via db2 CLIAffected if Installed version is 11.5.0 through 11.5.9, or 12.1.0 through 12.1.1
-
Confirm Db2 instance is runningRun 'db2 list active databases' or check db2pd -utilities outputAffected if An active Db2 instance exists on the system
-
Identify if vulnerable configuration is enabledReview db2diag.log for configuration patterns mentioned in IBM security bulletin; check DB CFG and DBM CFG parameters for specific settings that trigger the memory leak pathAffected if The specific configuration that enables the memory leak condition is present
-
Monitor for memory exhaustion symptomsCheck system memory usage (top, vmstat, or operating system memory monitoring) and review db2diag.log for 'Out of memory' or 'SQLAllocStmt' errorsAffected if Memory usage continuously grows without release or memory allocation failures appear in logs
User is affected if running a Db2 version 11.5.0-11.5.9 or 12.1.0-12.1.1 AND the specific vulnerable configuration is enabled, leading to observable memory exhaustion.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the IBM Db2 patch for this vulnerability or upgrade to a fixed version; review IBM's security bulletin for specific configuration workarounds if patches are not immediately available.
