Summary
SOEM (Simple Open EtherCAT Master), an open-source EtherCAT master library, is affected by this vulnerability. A malicious device on the network could trigger out-of-bounds memory reads that may leak sensitive data or crash the master application.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
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.
