CVE-2025-71410: CWE-770 in ATN-B1 CPDLC
CVE-2025-71410 is a vulnerability in the ATN-B1 CPDLC system where unnumbered disconnect and malformed Aviation Very High Frequency Link Control frames can terminate communication sessions. This disruption leads to loss of CPDLC functionality, forcing a fallback to voice communication and increasing controller workload. The attack can be executed remotely over radio frequency.
AI Analysis
Technical Summary
This vulnerability involves the improper handling of unnumbered disconnect (U DISC) and malformed link control frames in the ATN-B1 CPDLC system. Exploiting this flaw allows an attacker to terminate CPDLC sessions remotely via radio frequency, causing a loss of data link communication and necessitating reversion to voice communication methods. The vulnerability is classified under CWE-770 (Allocation of Resources Without Limits or Throttling).
Potential Impact
Successful exploitation results in termination of CPDLC sessions, loss of data link communication, and increased workload for air traffic controllers due to forced reversion to voice communication. This can degrade operational efficiency and potentially increase the risk of communication errors in air traffic management.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
