CVE-2025-43581
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 · uneditedSubstance3D - Sampler versions 5.0 and earlier are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. 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 confidenceAdobe Substance3D Sampler versions 5.0 and earlier contain an out-of-bounds write vulnerability in file parsing logic. When a user opens a specially crafted malicious file, the vulnerability allows an attacker to write data outside the bounds of allocated memory, potentially achieving arbitrary code execution in the context of the current user.

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 Adobe Substance3D Sampler is installedCheck system for Adobe Substance3D Sampler installation via Add/Remove Programs (Windows) or Applications folder (macOS), or search for the executable file in typical installation paths such as C:\Program Files\Adobe\Adobe Substance 3D Sampler on Windows or /Applications/Adobe Substance 3D Sampler on macOSAffected if The application is present on the system
-
Determine installed version numberOpen Adobe Substance3D Sampler and navigate to Help > About Adobe Substance3D Sampler, or right-click the executable file and select Properties > Details to view the product versionAffected if The version displayed is lower than 5.0.3 (for example, 5.0, 4.x, or earlier)
-
Confirm file parsing is in useIdentify whether the system user opens external files in Adobe Substance3D Sampler - the vulnerability is triggered during file parsing when opening specially crafted filesAffected if Users open external .sbsar, .sbs, or other supported asset files from untrusted sources in the application
A user is affected if Adobe Substance3D Sampler version 5.0.3 or earlier is installed AND the application is used to open external files, since the out-of-bounds write occurs during file parsing of a maliciously crafted file.

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 · scoped5.0.3
Update Substance3D Sampler to a version newer than 5.0 when a patch becomes available. Until then, refrain from opening untrusted or unexpected files in the application.
Substance 3D Sampler 5.0.3
- Open Adobe Creative Cloud desktop application or navigate to the Adobe Substance 3D Sampler download page at helpx.adobe.com
- Locate Substance 3D Sampler in your installed applications
- Check current installed version to confirm it is below 5.0.3
- Update or download Substance 3D Sampler version 5.0.3 or later from Adobe's official download page
- Install the updated version, following the on-screen prompts
- Restart the application if required after installation
