CVE-2023-28907
📋 TL;DR
This vulnerability allows an attacker with access to the MIB3 infotainment system's main OS to compromise the CPU core responsible for CAN message processing due to lack of memory isolation between cores. This affects Volkswagen Group vehicles with MIB3 infotainment units, specifically Skoda Superb III and other models using affected OEM part numbers. Attackers could potentially manipulate vehicle functions via the CAN bus.
💻 Affected Systems
- Volkswagen MIB3 infotainment system
- Skoda Superb III with MIB3
- Other VW Group vehicles with MIB3

⚠️ Risk & Real-World Impact
Worst Case
Full vehicle control compromise allowing manipulation of critical systems like braking, steering, or acceleration via CAN bus injection.
Likely Case
Unauthorized access to vehicle functions like door locks, climate control, or infotainment features.
If Mitigated
Limited impact if proper network segmentation and access controls prevent attackers from reaching the infotainment system.
🎯 Exploit Status
Requires initial access to main OS. Research presented at Black Hat EU 2024 demonstrates exploitation.
