Summary

CVE-2026-26071 is a medium-severity Race Condition (CWE-362) vulnerability in Linuxfoundation Everest. Its CVSS base score is 4.2 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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.

Vulnerability Data

EVerest is an EV charging software stack. Versions prior to 2026.02.0 have a data race leading to `std::string` concurrent access. with heap-use-after-free possible. This is triggered by EVCCID update (EV/ISO15118) and OCPP session/authorization events. Version 2026.02.0 contains a patch.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

UAF data race in network-triggered OCPP/ISO15118 paths enables remote exploitation of public EV charging endpoints.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Developer testing and evaluation (including dynamic analysis with race detectors) directly catches data races and use-after-free conditions before release.

prevent

Requires use of development standards and tools that enforce thread-safe coding and static/dynamic analysis for concurrent std::string access.

prevent

Memory protection mechanisms can mitigate exploitation of the resulting heap-use-after-free even if the race is triggered.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper synchronization primitives and concurrency testing that prevent race conditions.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover use-after-free issues via scanning or analysis but do not prevent their introduction.

PR.PS-02 partial match
prevents

Routine patching removes known use-after-free instances after they have been introduced in released software.

detects

Security testing can detect race conditions, but does not prevent them at design or coding time.

prevents

Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.

prevents

Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.

prevents

Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.

prevents

Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.

prevents

Change-management processes help ensure memory-safety fixes are deployed consistently.
