CVE-2026-64197

Code execution via unvalidated DSB parser write

Published Sep 3, 2026 · Updated Sep 4, 2026

Out-of-bounds write in Digilent DASYLab before 2026.0.0 allows attackers to execute code after a user opens a crafted .DSB file. The DSB parser fails to validate user-supplied data before writing it, causing a write past the end of an allocated data structure. A user must open the file, after which memory corruption can execute attacker-controlled code in that user's context.
