CVE-2026-16316: CWE-20 Improper input validation in OMICRON electronics GmbH OMICRON StationGuard
OMICRON StationGuard 4.00 contains an improper input validation vulnerability in its IEC 61850 Sampled Values (SV) frame processing. A specially crafted SV frame can cause the affected process to terminate, disrupting alert processing for Sampled Values traffic. The vulnerability does not affect overall system availability or the processing of other traffic types, and the process is automatically restarted, and the failure is immediately reported to the user.
AI Analysis
Technical Summary
CVE-2026-16316 describes an improper input validation vulnerability (CWE-20) in OMICRON StationGuard 4.00's IEC 61850 Sampled Values frame processing. Malformed Sampled Values frames can cause the specific process handling these frames to terminate, resulting in disruption of alert processing for Sampled Values traffic. The system continues to operate normally for other traffic types, and the affected process automatically restarts with immediate user notification of the failure. No patch or official remediation level is currently stated, and no known exploits have been reported.
Potential Impact
The vulnerability causes termination of the process responsible for IEC 61850 Sampled Values alert processing, temporarily disrupting alerts related to this traffic type. However, it does not impact overall system availability or processing of other traffic types. The process automatically restarts, minimizing downtime, and the failure is reported to the user, allowing for prompt awareness.
Mitigation Recommendations
No official patch or remediation level is currently provided by the vendor. The process affected by the vulnerability automatically restarts upon termination, and the failure is immediately reported to the user. Users should monitor for such alerts and follow vendor advisories for any future updates or patches addressing this issue.
