Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical flaw in the **Bosch Infotainment ECU** allows code execution.β¦
π‘οΈ **Root Cause**: **CWE-121** (Stack Buffer Overflow). The V850 processor has a defect when handling **custom protocol requests**. This memory corruption is the gateway to the exploit.
Q3Who is affected? (Versions/Components)
π **Affected**: **Bosch Infotainment System ECU**. Specifically used in **Nissan** vehicles (e.g., Nissan Leaf). π **Published**: Feb 15, 2026. Check your ECU vendor and vehicle model!
Q4What can hackers do? (Privileges/Data)
π **Hacker Power**: Full **Code Execution** on the Infotainment SoC and RH850 module. π‘ **Impact**: Can send **arbitrary CAN messages**.β¦
β οΈ **Threshold**: **LOW**. CVSS Vector: `AV:L/AC:L/PR:N/UI:N`. No authentication (PR:N), no user interaction (UI:N), low complexity (AC:L). Local access is likely required, but once inside, it's a straight shot.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Exploit Status**: No public PoC listed in the data. However, **Black Hat Asia 2025** presentation exists (Evdokimov). This suggests **academic/research-level exploitation** is known. Wild exploitation risk is rising.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Bosch Infotainment ECUs** in your vehicle's CAN bus. Look for V850/RH850 architecture signatures. Use CAN bus analyzers to detect abnormal custom protocol requests from the infotainment unit.
π§ **Workaround**: If no patch, **physically isolate** the Infotainment ECU from the critical CAN bus (if possible). Disable remote connectivity features.β¦
π₯ **Urgency**: **CRITICAL**. CVSS Score is **9.8** (H:C, H:I, H:A). Local access is easy. Impact is vehicle control. Treat this as a **high-priority security incident** for fleet managers and owners.
