CVE-2026-59701

Code execution via crafted BMP out-of-bounds read

Published Aug 11, 2026 · Updated Aug 11, 2026

Out-of-bounds read in Siemens Simcenter Femap before V2606.0001 allows attackers to execute code through a crafted BMP file. The BMP parser reads beyond its intended buffer, but Siemens has not published the affected routine or the unchecked BMP field. A user must open the file; successful exploitation runs code in the current process, while failed attempts can crash the application.
