CVE-2025-22884

Code execution via unchecked DVP buffer write

Published Apr 30, 2025 · Updated Aug 25, 2025

Stack-based buffer overflow in Delta Electronics ISPSoft 3.20 and earlier allows attackers to execute code by opening a crafted DVP file. The DVP parser fails to validate user-supplied data before writing past the end of an allocated stack buffer. Exploitation requires a user to open the malicious file and runs code in the context of the current ISPSoft process.
