CVE-2026-0956 is a vulnerability identified in Digilent's DASYLab software, a tool widely used for data acquisition and control applications. The root cause is an out-of-bounds read (CWE-125) triggered when the software attempts to load a corrupted file. This memory corruption flaw can lead to serious consequences, including unauthorized disclosure of sensitive information or execution of arbitrary code, which could allow an attacker to take control of the affected system. Exploitation requires that an attacker craft a malicious file and convince a user to open it, making user interaction necessary. The vulnerability affects all versions of DASYLab, indicating a fundamental flaw in the file parsing logic. The CVSS v3.1 base score of 7.8 reflects a high severity level, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are known, the potential for severe damage warrants immediate attention. The lack of available patches at the time of publication means users must rely on mitigation strategies until official fixes are released.

The vulnerability can have significant impacts on organizations using DASYLab, particularly in sectors relying on precise data acquisition and control such as manufacturing, research laboratories, and industrial automation. Successful exploitation could lead to leakage of sensitive data, disruption of critical processes, or full system compromise, undermining operational integrity and confidentiality. Given the high impact on confidentiality, integrity, and availability, attackers could manipulate data outputs or disrupt system functions, potentially causing financial loss, safety hazards, or reputational damage. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where users may open files from untrusted sources. The absence of known exploits currently reduces immediate threat but does not preclude future attacks as exploit code may be developed. Organizations worldwide using DASYLab are at risk until mitigations or patches are applied.

1. Educate users to avoid opening files from untrusted or unknown sources, especially in environments where DASYLab is used. 2. Implement strict file validation and scanning policies at email gateways and endpoint security solutions to detect and block malicious files targeting this vulnerability. 3. Employ application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 4. Monitor for updates from Digilent and apply patches promptly once available. 5. Consider network segmentation to isolate systems running DASYLab from general user environments to reduce exposure. 6. Use endpoint detection and response (EDR) tools to identify suspicious behavior indicative of exploitation attempts. 7. Maintain regular backups of critical data and system configurations to enable recovery in case of compromise. 8. If feasible, restrict DASYLab usage to trusted personnel and environments to minimize risk of malicious file introduction.
