CVE-2026-64195

Out-of-bounds write via malformed DSB parsing

Published Sep 3, 2026 · Updated Sep 4, 2026

Out-of-bounds write in DASYLab before 2026.0.0 allows attackers to corrupt process memory through a crafted .DSB file. The .DSB parser fails to validate file-supplied data before a write, allowing the operation to pass an allocated boundary. A user must open the file; the vendor has not specified whether the resulting corruption causes a crash, disclosure, or code execution.
