CVE-2026-0956
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 · uneditedThere is a memory corruption vulnerability due to an out-of-bounds read when loading a corrupted file in Digilent DASYLab. This vulnerability may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted file. This vulnerability affects all versions of Digilent DASYLab.
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 confidenceDigilent DASYLab contains a memory corruption vulnerability caused by an out-of-bounds read when parsing corrupted files. An attacker can craft a malicious file that, when opened by a victim, triggers the vulnerability leading to information disclosure or arbitrary code execution. All versions of DASYLab are affected.

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 DASYLab installationCheck system for presence of DASYLab software by searching for the application in installed programs (Windows: Add/Remove Programs, Programs and Features; or check common installation directories such as C:\Program Files\DASYLabs or C:\Program Files (x86)\DASYLabs)Affected if DASYLab is installed on the system
-
Identify installed DASYLab versionOpen DASYLab and navigate to Help > About, or check the version information in the Windows program properties, or locate the main executable (typically dasylab.exe) and view its file propertiesAffected if Any version of DASYLab is found (all versions are affected)
-
Confirm file parsing capabilityVerify that DASYLab is configured to open or import external data files, configuration files, or workspace files. Check application settings for file import/export functions and recent file associationsAffected if DASYLab can open or import external files (this is the attack vector)
-
Review file type associationsCheck which file extensions are associated with DASYLab (look at .dlb, .dsf, .dsd, or custom extension handlers in Windows Default Programs or file associations)Affected if DASYLab has registered file associations that could open untrusted files
If DASYLab is installed and can process external files, the environment is affected by this vulnerability when opening untrusted or corrupted files.

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 dataUsers should avoid opening untrusted files until an official patch is released. Organizations should implement file type validation and consider application sandboxing or network isolation for systems running DASYLab.
