CVE-2025-8474
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 · uneditedAlpine iLX-507 CarPlay Stack-based Buffer Overflow Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Alpine iLX-507 devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the Apple CarPlay protocol. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26318.
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 · high confidenceStack-based buffer overflow in Alpine iLX-507 CarPlay implementation allows root code execution via crafted user-supplied data copied without proper length validation to a fixed-size stack buffer. Physical proximity is required but no authentication.

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.
-
Confirm device model is Alpine iLX-507Check the product labeling, system information, or firmware identification on the head unit to verify the model number is exactly iLX-507 or Ilx-507Affected if Device is not an Alpine iLX-507 unit - different models are not affected by this CVE
-
Identify installed firmware versionAccess the head unit system settings or firmware information screen, typically found under Settings > System > Firmware Info or similar menu path, and record the firmware version numberAffected if Firmware version is not exactly 6.0.000 - only version 6.0.000 is listed as affected
-
Verify CarPlay functionality has been enabled or usedCheck if CarPlay is listed as enabled in the head unit settings, or review connection history for USB devices that may have triggered CarPlay activationAffected if CarPlay has never been enabled or connected - the buffer overflow occurs during CarPlay data processing, so unused CarPlay would not trigger the vulnerable code path
-
Assess physical exposure to untrusted devicesEvaluate whether the vehicle or USB ports are accessible to unauthorized individuals who could connect malicious devicesAffected if Physical proximity requirement means the vulnerability is only exploitable by someone with physical access to connect a crafted device to the CarPlay USB port
User is affected if they have an Alpine iLX-507 unit running firmware version 6.0.000 with CarPlay enabled and the USB ports are accessible to untrusted individuals.

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 dataApply vendor-provided firmware patch when available; until then, limit physical access to the vehicle and avoid connecting untrusted devices to CarPlay USB ports.
