Technical details

CVE-2026-64198 is an out-of-bounds read vulnerability (CWE-125) in DASYLab's DSB file parser caused by improper validation of user-supplied data. The vulnerability occurs during file handling when parsing specially crafted DSB files, resulting in reads a few bytes past the end of an allocated heap buffer. The attack vector is local and requires user interaction—an attacker must trick a user into opening a malicious DSB file. Successful exploitation can result in information disclosure or arbitrary code execution in the context of the DASYLab process. The vulnerability is fixed in DASYLab version 2026.0.0 (Build 65) and later.
