SOEM version 2.0.0 and earlier contains a vulnerability during device configuration where a malicious device can cause memory corruption. The software writes configuration data to a fixed-size array without checking if the array index exceeds its maximum size of EC_MAXFMMU entries. A device presenting more than EC_MAXFMMU configuration blocks can force writes beyond the array boundary, corrupting adjacent memory structures and potentially disrupting subsequent operations.
