{"id":"CVE-2026-82947","state":"PUBLISHED","title":"Multiple Out-of-Bounds Reads in Frame Processing","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.
