Security readout for executives and security teams
Plain-English summary
CVE-2026-22541 is a denial-of-service issue in EFACEC QC 60/90/120 EV chargers, version 8. A large volume of ICMP requests can disrupt a board that controls EV interfaces, making the charger unable to function correctly. The published record rates this high severity.
Executive priority
Prioritize if affected chargers support revenue, fleet operations, or public charging services. The business risk is service outage, not data theft based on current sources. Treat as high priority for exposed operational networks.
Technical view
The CVE describes CWE-400 uncontrolled resource consumption. Network-based, unauthenticated ICMP traffic can cause high availability impact on a required EV charger control board. CVSS 4.0 score is 8.2 with AV:N, AC:L, PR:N, UI:N, VA:H. The record lists EFACEC QC 60/90/120 version 8 as affected.
Likely exposure
Exposure is most likely where affected EFACEC chargers are reachable from untrusted or poorly controlled networks that allow ICMP to the charger. Internet exposure is not stated in the sources and should be verified locally.
Exploitation context
The source describes denial of service from massive ICMP requests. It does not report active exploitation, public exploit availability, or CISA KEV listing. Impact is availability-focused; confidentiality and integrity impacts are not indicated by the CVSS vector.
Researcher notes
Evidence is limited to the CVE record and a Thales reference. No patch, workaround, exploit details, or affected firmware build granularity beyond version 8 is provided. Default status is listed as unaffected for other versions/products.
Mitigation direction
- Check EFACEC or relevant vendor guidance for fixes or configuration recommendations.
- Restrict ICMP access to charger management and control networks.
- Segment EV charging infrastructure from public and corporate user networks.
- Apply rate limiting or filtering at upstream routers and firewalls.
- Monitor charger availability and network traffic anomalies.
Validation and detection
- Inventory EFACEC QC 60/90/120 chargers and identify version 8 deployments.
- Confirm whether ICMP can reach chargers from untrusted networks.
- Review firewall, router, and NAC rules protecting charger networks.
- Check logs for ICMP spikes correlated with charger outages.
- Track CVE and vendor references for patch or advisory updates.
