CVE-2025-24439
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 4.5.2 and earlier are affected by a Heap-based Buffer Overflow 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 4.5.2 and earlier contain a heap-based buffer overflow vulnerability that can be triggered when a user opens a specially crafted malicious file. This memory corruption flaw allows an attacker to achieve arbitrary code execution within the context of the victim's user session.

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 Adobe Substance3D Sampler installationCheck common installation paths: Windows typically at C:\Program Files\Adobe\Adobe Substance 3D Sampler\ or C:\Program Files (x86)\Adobe\Adobe Substance 3D Sampler\. On macOS, check /Applications/Adobe Substance 3D Sampler/. Use file explorer or command: dir "C:\Program Files\Adobe" or ls /Applications/ | grep -i substanceAffected if The software is not found in standard installation directories - if absent, likely not affected in this location
-
Identify the installed version numberRight-click the executable (Substance 3D Sampler.exe on Windows, Adobe Substance 3D Sampler.app on macOS), select Properties, then Details tab. Alternatively, locate a version file in the installation folder or run: reg query "HKLM\SOFTWARE\Adobe\Substance 3D Sampler" /v VersionAffected if No version information is returned or the version cannot be determined
-
Compare version against affected rangeThe affected version range is anything below 5.0, specifically 4.5.2 and earlier. Compare your installed version: if it reads 4.x.x or any version number less than 5.0.0, it falls within the affected rangeAffected if The installed version is 4.5.2, 4.5.1, 4.5.0, 4.4.x, or any other version where the major version is 4, or any version < 5.0.0
-
Verify the application executable exists and is accessibleConfirm the main executable file exists in the installation directory. On Windows, verify Substance3DSampler.exe is present. This confirms the application can be launched and potentially used to open filesAffected if The executable exists and can be run, meaning the vulnerability is present if the version is < 5.0
If Adobe Substance3D Sampler is installed with any version lower than 5.0.0, the environment is vulnerable to this heap-based buffer overflow when opening malicious files.
