Answer in brief
CVE-2026-16316 records a Medium severity (CVSS 4.3) vulnerability in Malformed IEC 61850 Sampled Values frames cause partial denial of service in StationGuard. The current sources do not mark it as known exploited. The current feed maps OMICRON electronics GmbH/OMICRON StationGuard (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 4.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
