CVE-2025-2762
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCarlinKit CPC200-CCPA Missing Root of Trust Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of CarlinKit CPC200-CCPA devices. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the configuration of the application system-on-chip (SoC). The issue results from the lack of a properly configured hardware root of trust. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the boot process. Was ZDI-CAN-25948.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis vulnerability exists in CarlinKit CPC200-CCPA devices where the application SoC lacks a properly configured hardware root of trust. An attacker with existing low-privileged code execution can exploit this configuration flaw to escalate privileges and execute arbitrary code during the boot process, bypassing secure boot protections.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify the installed firmware versionAccess the Carlinkit device settings or firmware information page, typically found in the Autokit companion app or device web interface, and record the exact firmware build number.Affected if The installed version is exactly 2024.01.19.1541, as this is the only confirmed affected version for this product.
-
Confirm secure boot is not bypassedCheck the device boot configuration or security settings for the secure boot status. This may be accessible via the device debug port, UART console, or configuration file in the firmware dump.Affected if Secure boot shows as disabled, bypassed, or not properly enforced in the boot configuration.
-
Inspect hardware root of trust configurationExamine the SoC configuration data, typically stored in eFuse, OTP memory, or boot-related configuration files accessible through the device firmware or debug interface.Affected if The hardware root of trust is not properly configured, missing, or disabled in the SoC settings.
-
Check for weak boot chain integrityReview boot log files or boot sequence documentation to verify if each stage of the boot process validates the next stage's signature before execution.Affected if The boot chain does not validate signatures at each stage, allowing unsigned or modified boot components to execute.
-
Determine if low-privileged code execution is possibleAssess whether any applications, services, or interfaces on the device allow code execution with limited privileges (e.g., guest user, limited app permissions).Affected if Any form of low-privileged code execution is possible, as this is a prerequisite condition for exploiting this vulnerability to achieve privilege escalation.
A user is affected if their Carlinkit Autokit firmware is version 2024.01.19.1541 and the device lacks a properly configured hardware root of trust that would prevent a low-privileged attacker from escalating privileges during the boot process.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement a proper hardware root of trust in the SoC configuration and verify the secure boot chain; this requires firmware updates and likely reconfiguration of the boot security architecture.
