Digilent DASYLab DSB File Parsing Out-of-Bounds Write Remote Code Execution Vulnerability

IdentifiersCVE-2026-0954CWE-787· Out-of-bounds Write

CVE-2026-0954 is a memory corruption vulnerability in Digilent DASYLab caused by an out-of-bounds write during parsing of corrupted or specially crafted DSB files. The flaw stems from improper validation of user-supplied data while loading a DSB file, allowing writes past the end of an allocated data structure. Successful exploitation can lead to information disclosure or arbitrary code execution in the context of the current process. The issue affects all versions of Digilent DASYLab referenced in the provided content.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A successful exploit can corrupt process memory and enable arbitrary code execution in the security context of the user running Digilent DASYLab. Depending on exploit reliability and runtime conditions, the vulnerability may also result in information disclosure. Because exploitation is triggered through malicious file parsing, this can be used to compromise a workstation when a user opens a crafted .DSB file.

Mitigation

If you can’t patch tonight, do this now.

Until patches are fully deployed, prevent users from opening untrusted or unsolicited .DSB files, especially those received via email, downloads, or shared repositories. Restrict DASYLab use to trusted project files, apply application allowlisting and endpoint protections to reduce execution of malicious payloads, and limit user privileges so that successful exploitation yields less impact. Where feasible, isolate systems used to process externally supplied DSB files.

Remediation

Patch, then assume compromise.

Apply the vendor-issued update that corrects the DSB file parsing flaw in Digilent DASYLab. The provided content states that Digilent issued an update to address the vulnerability; affected organizations should upgrade to the fixed release identified by the vendor and National Instruments security update guidance.
