Summary

CVE-2025-68141 is a high-severity NULL Pointer Dereference (CWE-476) vulnerability in Linuxfoundation Everest. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 16th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

CVE-2025-68141 is a null pointer dereference vulnerability (CWE-476) in the EVerest EV charging software stack, affecting versions prior to 2025.10.0. The issue arises during deserialization of a DC_ChargeLoopRes message containing Receipt and TaxCosts data, where the vector<DetailedTax>tax_costs in the target Receipt structure is accessed out of bounds. This occurs specifically in the templated convert method: template <> void convert(const struct iso20_dc_DetailedTaxType& in, datatypes::DetailedTax& out), leading to module termination. The vulnerability has a CVSS v3.1 base score of 7.4 (AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H).

An adjacent network attacker with no privileges or user interaction required can exploit this by sending a specially crafted DC_ChargeLoopRes message. Successful exploitation triggers a null pointer dereference, causing the affected EVerest module to crash, which shuts down all EVerest processes and modules. This results in a high-impact denial of service, rendering all connected Electric Vehicle Supply Equipment (EVSE) inoperable.

The GitHub Security Advisory at https://github.com/EVerest/everest-core/security/advisories/GHSA-ph4w-r9q8-vm9h details the issue and confirms that upgrading to version 2025.10.0 resolves the vulnerability by addressing the out-of-bounds access in the deserialization logic.

Vulnerability Data

EVerest is an EV charging software stack. Prior to version 2025.10.0, during the deserialization of a `DC_ChargeLoopRes` message that includes Receipt as well as TaxCosts, the vector `<DetailedTax>tax_costs` in the target `Receipt` structure is accessed out of bounds. This occurs…

in the method `template <> void convert(const struct iso20_dc_DetailedTaxType& in, datatypes::DetailedTax& out)` which leads to a null pointer dereference and causes the module to terminate. The EVerest processes and all its modules shut down, affecting all EVSE. Version 2025.10.0 fixes the issue.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including static analysis) directly finds null-dereference bugs before deployment.

Documented development standards and tools can enforce null-safety rules and safe pointer usage.

Engineering principles can mandate defensive coding such as explicit null checks before dereference.
