CVE-2026-64198: CWE-125 Out-of-bounds read in measX DASYLab
Description
There is an out-of-bounds read vulnerability in DASYLab due to improper validation of user-supplied data. This results in a read a few bytes past the end of an allocated heap buffer during file handling. Successful exploitation requires an attacker to get a user to open a specially crafted .DSB file. This issue affects all versions before 2026.0.0.

Technical Analysis
This vulnerability in measX DASYLab involves an out-of-bounds read (CWE-125) due to insufficient validation of user input during file handling. Specifically, when a user opens a maliciously crafted .DSB file, the software reads beyond the allocated heap buffer boundary by a few bytes. This flaw affects all versions prior to 2026.0.0. The CVSS 4.0 vector indicates local attack vector, low attack complexity, no privileges required, user interaction needed, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to reading memory beyond the intended buffer, potentially exposing sensitive information or causing application instability. However, exploitation requires user interaction by opening a crafted file. 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. Since no official fix or patch links are provided, users should avoid opening untrusted .DSB files and monitor vendor communications for updates.
