A high-severity flaw in the Bluetooth communication stack of Bosch Infotainment ECUs allows for potential remote compromise of the device by attackers within Bluetooth range.

This flaw exists within the Bluetooth stack developed by Alps Alpine and integrated into Bosch Infotainment units. With a CVSS score of 8.8, the vulnerability likely involves improper handling of Bluetooth packets, which could lead to memory corruption or unauthorized command execution.

The impact of this vulnerability includes potential unauthorized access to the vehicle's multimedia system and associated user data. A CVSS score of 8.8 justifies its classification as a high-priority risk, as it could lead to significant reputational damage for the manufacturer and privacy concerns for vehicle owners.

Immediate Action: Install the latest software updates from the vehicle manufacturer that include the patched version of the Bosch/Alps Alpine Bluetooth stack.

Proactive Monitoring: Review system logs for failed or unusual Bluetooth pairing attempts and monitor for unexpected system reboots or infotainment crashes.

Compensating Controls: Limit the visibility of the vehicle's Bluetooth system and remove any unknown or unnecessary paired devices from the infotainment system's memory.

Public Exploit Available: false

This vulnerability represents a significant entry point for attackers targeting vehicle electronics. It is essential to apply the primary remediation—the vendor's software patch—immediately to mitigate the risk of remote exploitation via the Bluetooth interface.
