CVE-2025-57778
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 an out of bounds write vulnerability due to improper bounds checking resulting in an invalid source address when parsing a DSB file with Digilent DASYLab. This vulnerability may result in arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted DSB file. The vulnerability affects all versions of 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 confidenceAn out-of-bounds write vulnerability exists in Digilent DASYLab's DSB file parsing routine due to improper bounds checking. The vulnerability allows an attacker to trigger an invalid source address write by providing a specially crafted DSB file, potentially achieving arbitrary code execution.

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.
-
Check if Ni Dasylab is installedSearch for Digilent Dasylab or Ni Dasylab in installed programs (Windows: Control Panel > Programs and Features, or check C:\Program Files\National Instruments\DASYLAB or similar installation directories)Affected if Ni Dasylab software is present on the system
-
Identify installed Dasylab versionCheck the version of the installed Dasylab software through the application (Help > About) or by locating the executable and viewing its propertiesAffected if Any version of Ni Dasylab is installed (all versions are affected)
-
Check DSB file handling capabilityVerify if Dasylab can import or open DSB files by checking file import options or file type associations within the applicationAffected if DSB file import or parsing functionality is available and enabled in Dasylab
-
Review recent DSB file activityCheck system for recently opened or accessed .dsb files, particularly in user-accessible directories such as Documents, Downloads, or shared network locationsAffected if DSB files have been opened or processed by the Dasylab software
If Ni Dasylab is installed and capable of processing DSB files, the environment is affected by this vulnerability when a specially crafted DSB file is opened.

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 not open DSB files from untrusted sources until a vendor patch is available. Organizations should consider network segmentation and endpoint controls to limit exposure to this file-based attack vector.
