CVE-2026-22923

Code execution via PDF export stack overflow

Published Feb 10, 2026 · Updated Feb 10, 2026

Stack-based buffer overflow in Siemens Designcenter NX before V2512 allows local users to execute arbitrary code during PDF export. Siemens identifies missing validation of internal data in the PDF export path, but does not disclose the affected function or copy operation. Exploitation requires local access and interaction with PDF export; successful exploitation runs code in the NX process context.
