CVE-2025-3632
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 4769 Developers Toolkit 7.0.0 through 7.5.52 could allow a remote attacker to cause a denial of service in the Hardware Security Module (HSM) due to improper memory allocation of an excessive size.
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 · moderate confidenceThe IBM 4769 Developers Toolkit versions 7.0.0 through 7.5.52 contains a memory allocation vulnerability where the software allows allocation of excessive memory sizes based on attacker-controlled input, leading to HSM resource exhaustion and denial of service.

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.
-
Identify installed IBM 4769 Developers Toolkit versionLocate the toolkit installation directory and check the version manifest, about dialog, or version file. Common locations include the installation root or a /lib directory containing versioned JAR files or binary manifests.Affected if The installed version is 7.0.0 through 7.5.52 (any version >= 7.0.0 but < 7.5.62)
-
Confirm the toolkit is actively deployed and runningCheck for running processes related to the IBM 4769 Developers Toolkit, such as HSM client services, cryptographic daemon processes, or API servers that utilize the toolkit.Affected if The toolkit software is currently running and processing requests
-
Determine if the toolkit API or service is network-accessibleReview network configuration, firewall rules, and service binding settings to identify whether the toolkit endpoints are exposed to untrusted networks or external attackers.Affected if The service is reachable from untrusted networks or allows attacker-controlled input to trigger memory allocation operations
You are affected if the IBM 4769 Developers Toolkit version is 7.0.0 through 7.5.52 and the service is actively running and accessible to supply attacker-controlled input that triggers excessive memory allocation.

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.
dbcve · scoped7.5.62
Apply the available IBM fix for this vulnerability (refer to IBM security bulletin for specific patch version). Before deployment, validate the patch in a non-production HSM environment to ensure compatibility with existing cryptographic operations and key management workflows.
7.5.62 or later
- 1. Identify the current installed version of IBM 4769 Developers Toolkit using system inventory or version check utilities
- 2. Schedule a maintenance window for the upgrade process
- 3. Create a complete backup of all HSM configurations, keys, and critical data
- 4. Download IBM 4769 Developers Toolkit version 7.5.62 or later from IBM's official support portal
- 5. Stop all services and applications that depend on the IBM 4769 Developers Toolkit
- 6. Install the updated version 7.5.62 or later following IBM's official installation documentation
- 7. Restart the HSM services and verify the toolkit is operational
- 8. Validate that the memory allocation issue is resolved and the HSM is functioning normally
