CVE-2026-21354
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 · uneditedDNG SDK versions 1.7.1 2410 and earlier are affected by an Integer Overflow or Wraparound vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to cause the application to crash or become unresponsive. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
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 confidenceThe DNG SDK versions 1.7.1 2410 and earlier contain an integer overflow or wraparound vulnerability during image file processing. When a victim opens a specially crafted malicious DNG file, the integer overflow can cause the application to crash or become unresponsive, resulting in 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.
-
Locate DNG SDK installationSearch for files named 'dng' or 'dng_sdk' in common installation directories such as /usr/local/lib, /opt, or C:\Program Files. Also check for applications that bundle the DNG SDK by searching for 'dng' related files or libraries.Affected if The DNG SDK or any application bundling it is found on the system.
-
Identify the DNG SDK versionLook for version information in SDK documentation, readme files, or library metadata. Check the DLL or shared library properties if the SDK is deployed as a binary. The version may be embedded in file properties or displayed in application about dialogs.Affected if A version number of 1.7.1 2410 or earlier is found, or no version is displayed (indicating an old release).
-
Verify SDK version against affected rangeCompare the installed version to the affected range: versions prior to 1.7.2 (including 1.7.1 2410 and earlier) are vulnerable.Affected if The installed version is lower than 1.7.2.
-
Determine if DNG file processing is enabledIdentify applications or services that use the DNG SDK to process image files. Check configuration files, application logs, or running processes that handle DNG file formats.Affected if The SDK is actively used to process DNG files from any source.
If the DNG SDK version is 1.7.1 2410 or earlier and is used to process DNG files, the environment is affected by this vulnerability.

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 · scoped1.7.2
Update the DNG SDK to a version newer than 1.7.1 2410 once a patch is available. Until then, exercise caution when opening DNG files from untrusted sources.
DNG Software Development Kit version 1.7.2
- 1. Identify all locations where the DNG Software Development Kit is referenced in your project (e.g., package.json, pom.xml, requirements.txt, or direct library imports)
- 2. Locate the current DNG SDK dependency version declaration
- 3. Update the DNG SDK dependency to version 1.7.2 or later
- 4. Run dependency resolution to fetch the updated library
- 5. Rebuild the application to ensure the new SDK version is compiled in
- 6. Test the application to verify functionality remains intact after the upgrade
