CVE-2026-0956

Code execution via DSA parser bounds error

Published Mar 13, 2026 · Updated Mar 13, 2026

An out-of-bounds read in all versions of Digilent DASYLab allows attackers to execute code through a crafted DSA file. The DSA parser insufficiently validates user-supplied data and reads past the end of an allocated data structure. Exploitation requires a user to open the file, and resulting code runs in the context of the DASYLab process.
