AI Threat Summary
CVE-2026-82944 is a high-severity vulnerability with a CVSS score of 8.8 affecting the target software. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.
Description
SOEM version 2.0.0 and earlier contains a vulnerability in multi-segment data transfers where a malicious device can overflow memory buffers. The software checks the total size only once at the beginning, but doesn't track the cumulative size as multiple segments arrive. An attacker can declare a small initial size to pass validation, then send additional segments that exceed the allocated buffer. This allows the attacker to write controlled data beyond buffer boundaries, potentially enabling code execution.
