CVE-2026-44411

Code execution via uninitialized pointer access

Published May 12, 2026 · Updated May 12, 2026

Uninitialized pointer access in Siemens Solid Edge SE2026 before V226.0 Update 5 allows attackers to execute code via a crafted PAR file. The PAR-file parser accesses an uninitialized pointer while processing attacker-controlled file data; Siemens has not disclosed the specific function. Execution requires a user to open the malicious PAR file, and resulting code runs with the current process's privileges.
