CVE-2025-40829

Code execution via uninitialized SLDPRT parsing

Published Dec 12, 2025 · Updated Dec 12, 2025

Uninitialized memory use in Simcenter Femap before 2512 allows attackers to execute code when a crafted SLDPRT file is opened. The SLDPRT parser consumes an uninitialized memory resource while processing file content; Siemens has not disclosed a narrower function or field. Exploitation requires a user to open the malicious file, and code runs with the current process's privileges.
