CVE-2026-16316
MediumCVSS 4.3Summary
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.
Risk Assessment
An attacker could disrupt monitoring of Sampled Values traffic, potentially delaying incident detection in the power grid, but the system restarts automatically and reports the issue.
Recommendation
Update to the latest version of StationGuard and monitor process failure alerts.
