Detailsinfo

A vulnerability, which was classified as critical, was found in RT-Labs AB SOEM up to 2.0.0. Affected is an unknown function of the component Frame Processing. The manipulation of the argument offset with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at rt-labs.com. This vulnerability is traded as CVE-2026-82947 since 08/31/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit.
