Go to dashboardSOEM, an EtherCAT master library, uses length and offset values from device frames without checking them against buffer sizes. A malicious EtherCAT device can make the master read outside its buffers, leaking memory contents or crashing the process.
Summary written from the sources below. Check the originals before acting.

Teams running SOEM as an EtherCAT master on industrial or robotics controllers, where the master talks to attached field devices. The exposure requires a malicious or compromised device on the EtherCAT bus, so systems with no untrusted devices on that network are less exposed. The sources do not say which applications embed SOEM.

2.0.0 and earlier are affected.2.0.0; the sources do not name the fixed version.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
SOEM version 2.0.0 and earlier contains multiple vulnerabilities in frame processing where a malicious device can cause the master to read data outside allocated buffers. The software uses length and offset values from device messages without validating them against buffer sizes. This can cause the master to access invalid memory locations, potentially disclosing sensitive information or causing crashes.
