CVE-2024-6029
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 · uneditedTesla Model S Iris Modem Race Condition Firewall Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass the firewall on the Iris modem in affected Tesla Model S vehicles. Authentication is not required to exploit this vulnerability. The specific flaw exists within the firewall service. The issue results from a failure to obtain the xtables lock. An attacker can leverage this vulnerability to bypass firewall rules. Was ZDI-CAN-23197.
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 is a race condition vulnerability in the Iris modem's firewall service on affected Tesla Model S vehicles. The flaw allows network-adjacent attackers to bypass firewall rules due to the firewall service's failure to properly obtain the xtables lock before processing rules. No authentication is required for exploitation.

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.
-
Identify vehicle modelDetermine if the target vehicle is a Tesla Model S by checking the vehicle identification or system information.Affected if The vehicle is not a Tesla Model S, as this vulnerability only affects that specific model.
-
Check firmware versionRetrieve the current firmware version from the vehicle's system settings or diagnostic interface and compare it to 2024.2.3.Affected if The installed firmware version is lower than 2024.2.3.
-
Verify Iris modem presenceConfirm that the vehicle is equipped with an Iris modem by examining the modem hardware identification or network configuration.Affected if The Iris modem is not present in the vehicle, as the vulnerability exists in the Iris modem's firewall service.
-
Inspect firewall service configurationExamine the firewall service settings on the Iris modem to determine if the xtables lock is being properly obtained before rule processing.Affected if The firewall service is configured and the xtables lock handling cannot be verified or shows race condition potential.
A user is affected if they own a Tesla Model S with firmware version lower than 2024.2.3 that contains an active Iris modem with the vulnerable firewall service.

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 data2024.2.3
Apply any available Tesla firmware updates for the Iris modem. As a defensive measure, restrict network access to the vehicle's modem interface and monitor for anomalous traffic patterns until an official patch is available.
