# CVE-2026-82947: Multiple Out-of-Bounds Reads in Frame Processing

Status: published. Published: 2026-10-26. Updated: 2026-11-02.

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.
