CVE-2025-68134
Published: 21 January 2026
Summary
CVE-2025-68134 is a high-severity Improper Input Validation (CWE-20) vulnerability in Linuxfoundation Everest. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 24.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-11 (Error Handling).
Deeper analysis
CVE-2025-68134 is a vulnerability in EVerest, an open-source EV charging software stack, affecting versions prior to 2025.10.0. The issue arises from the frequent use of the assert() function for error handling, which causes individual modules to crash (CWE-20: Improper Input Validation). This is exacerbated by the EVerest manager's behavior, which shuts down all other modules and exits upon any module termination, resulting in a denial-of-service condition. 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 attacker with adjacent network access can exploit this vulnerability with low attack complexity, requiring no privileges or user interaction. By triggering an assert() failure in a module—such as through malformed inputs or unexpected conditions—the attacker causes the module to crash, prompting the manager to terminate all modules and exit. This leads to a high-impact denial of service on the affected EV charging system. In multi-EVSE (Electric Vehicle Supply Equipment) deployments managed by a single instance, the outage impacts other users sharing the manager.
The GitHub security advisory (GHSA-cxc5-rrj5-8pf3) at https://github.com/EVerest/everest-core/security/advisories/GHSA-cxc5-rrj5-8pf3 confirms that version 2025.10.0 resolves the issue by addressing the improper use of assert() for error handling. Security practitioners should prioritize upgrading to this version or later to mitigate the denial-of-service risk.

Vulnerability details
EVerest is an EV charging software stack. Prior to version 2025.10.0, the use of the `assert` function to handle errors frequently causes the module to crash. This is particularly critical because the manager shuts down all other modules and exits…

when any one of them terminates, leading to a denial of service. In a context where a manager handles multiple EVSE, this would also impact other users. Version 2025.10.0 fixes the issue.

Why these techniques?
Vulnerability directly enables Endpoint DoS via application/system exploitation by triggering assert failures through malformed input, causing full manager shutdown.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of inputs to reject malformed data before it reaches assert() calls that trigger module crashes.
Mandates proper error-handling routines instead of assert() so that invalid conditions do not cause abrupt module termination.
Requires the system to fail in a known safe state, preventing the manager from shutting down all modules and producing a full DoS.
