Out-of-Bounds Write in Digilent DASYLab Enables Code Execution

Executive Summary

CVE-2026-0954 is a memory corruption vulnerability in Digilent DASYLab software caused by an out-of-bounds write when loading a corrupted .DSB file.

This means that when the software parses a specially crafted DASYLab file, it writes data outside the intended memory boundaries, which can corrupt memory.

Exploitation requires a user to open a malicious .DSB file, leading to potential information disclosure or arbitrary code execution.

Impact Analysis

If exploited, this vulnerability can allow an attacker to disclose sensitive information or execute arbitrary code on the affected system.

However, exploitation requires local user interaction, meaning the attacker must convince a user to open a malicious file.

There is no remote exploitation possible, but successful exploitation could compromise confidentiality, integrity, and availability of the system.
