Answer in brief
CVE-2025-71409 records a Unknown severity vulnerability in No Authentication for Very High Frequency Data Link messages used in CPDLC. The current sources do not mark it as known exploited. The current feed maps ATN-B1/CPDLC (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
