Memory disclosure via DSB string-conversion over-read
Published Sep 3, 2026 · Updated Sep 4, 2026
Out-of-bounds read in DASYLab before 2026.0.0 allows attackers to expose process memory by inducing a user to open a crafted .DSB file. During string conversion, the DSB parser fails to validate user-supplied data and reads past the end of an allocated heap buffer. Exploitation requires user interaction with an untrusted local file, with process-memory disclosure as the bounded consequence.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
