Technical Analysis
CVE-2026-64198 is an out-of-bounds read vulnerability (CWE-125) in measX DASYLab caused by insufficient validation of user-supplied data during file handling. Specifically, opening a crafted .DSB file can trigger reading beyond the end of an allocated heap buffer, potentially leading to information disclosure or application instability. This vulnerability affects all versions prior to 2026.0.0. Exploitation requires local user interaction (opening the malicious file) and no privileges are required. The CVSS 3.1 base score is 8.5, reflecting high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to reading memory beyond allocated buffers, which may disclose sensitive information or cause application crashes. The vulnerability requires a user to open a malicious .DSB file, so social engineering is necessary. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should avoid opening untrusted or unexpected .DSB files to prevent exploitation.
