Summary of Security Advisory

A high-severity vulnerability (CVE-2025-2082) in Tesla Model 3’s Vehicle Controller Security (VCSEC) module allows attackers within wireless range to remotely execute arbitrary code by exploiting a flaw in the Tire Pressure Monitoring System (TPMS)

Overview 

This provides potentiality in giving access to critical vehicle controls; Tesla has addressed the issue in firmware version 2024.14. 

Technical Summary 

The vulnerability lies in the VCSEC module, responsible for security functions like immobilization, door locking, and TPMS monitoring.

An integer overflow occurs when the VCSEC processes malformed certificate responses transmitted via the TPMS subsystem. Exploiting this flaw enables memory corruption, leading to remote code execution.

The attack does not require user interaction or authentication and can be carried out over adjacent wireless interfaces such as Bluetooth Low Energy (BLE) or Ultra-Wideband (UWB).

Once compromised, attackers may issue unauthorized commands to the Controller Area Network (CAN) bus, which governs safety-critical systems including braking, steering, and acceleration. 

Remediation: 

• Update Tesla Firmware: Owners should update firmware version 2024.14 via the vehicle’s touchscreen or over-the-air (OTA) updates. 

• Avoid Wireless Threats: Refrain from connecting to unknown BLE/UWB networks and using unauthorized TPMS accessories. 

Conclusion: 
This vulnerability demonstrates how auxiliary vehicle systems like TPMS can serve as entry points for serious security breaches. While Tesla’s prompt patch release, reflects good incident response, this case underscores the urgency for ongoing scrutiny of wireless automotive components. Owners must apply the firmware update and maintain secure update practices to reduce the risk of exploitation.
