CVE-2026-22541 is a high-severity vulnerability affecting the EVCharger, specifically targeting its control board. This vulnerability allows the massive sending of ICMP requests, which can cause a denial of service (DoS) on the device's control interfaces. The implications of such an attack are significant, as it prevents the charger from functioning correctly, leading to potential service disruptions. Organizations utilizing EVChargers should be aware of this vulnerability, as it poses a risk to operational continuity.
With a CVSS score of 8.2, classified as high severity, this vulnerability requires organizations to prioritize remediation actions. Attackers may leverage this weakness to impact the availability of charging stations, which is particularly concerning given the increasing reliance on electric vehicles and their infrastructure. As such, organizations should address this vulnerability in their priority patch cycle to mitigate potential risks.
Currently, this vulnerability is marked as deferred, indicating that while it is recognized, further action may be pending from the vendor or relevant authorities. However, organizations should not delay in assessing their exposure and implementing necessary safeguards, especially since there are no known public exploits at this time.
Organizations should prioritize patching immediately. Understanding the operational risks associated with such vulnerabilities is critical in maintaining not only the functionality of electric vehicle infrastructure but also the trust of users relying on these services.
Vulnerability Details
The vulnerability described in CVE-2026-22541 is attributed to the massive sending of ICMP requests that leads to a denial of service on the EVCharger control board. This condition is critical as it directly impacts the operational capabilities of the charging stations, making it crucial for the control board to function correctly. The vulnerability has a CVSS score of 8.2, reflecting its high severity classification. This score indicates the potential for significant disruption if exploited. The vulnerability was published on January 7, 2026, and is classified under CWE-400, which stands for 'Uncontrolled Resource Consumption.'
Technical Analysis
The root cause of CVE-2026-22541 lies in the inability of the EVCharger to handle excessive ICMP requests, which are typically used for network diagnostics. The attack vector is classified as network-based, with low attack complexity and no privileges required for execution. This means that attackers can potentially execute a denial of service without needing any specific access to the system. Moreover, user interaction is not required, making this vulnerability particularly appealing for exploitation.
The impact of this vulnerability is significant in terms of availability, as it can lead to complete service disruption of the EVCharger. However, it does not affect confidentiality or integrity. Organizations must consider the potential financial and reputational damage that could arise from service outages caused by this vulnerability.
Risk & Impact Analysis
Risk to organizations includes operational downtime and financial losses associated with disrupted EV charging services. The blast radius of this vulnerability is considerable, given the growing number of electric vehicles and the reliance on charging infrastructure. Organizations should assess their exposure and prioritize patching based on the CVSS score and the potential impact on their operations.
Given that the CVE is not currently listed as actively exploited, organizations still need to act promptly to mitigate risks. The availability impact is classified as high, underscoring the urgency of addressing this vulnerability in the patch cycle. Organizations should regularly monitor the status of this CVE for updates and potential exploit details.
