CVE-2026-37539 — AI Deep Analysis Summary

🚨 **Essence**: Cannelloni v2.0.0 suffers from a **Buffer Overflow**. 📉 **Consequences**: Remote attackers can trigger **Denial of Service (Crash)** or potentially execute **Arbitrary Code**.…

🛡️ **Root Cause**: The flaw lies in **parser.cpp** (`parseCANFrame`) and **decoder.cpp** (`decodeFrame`). These functions mishandle **CAN frames**, leading to memory corruption.…

📦 **Affected**: Specifically **Cannelloni v2.0.0**. 🚫 **Vendor/Product**: Listed as 'n/a' in the data, but the tool is clearly a CAN bus analyzer/decoder. Check if you are running this exact version!

💻 **Attacker Capabilities**: With **CVSS 3.1 (Critical)**, impacts are High on Confidentiality, Integrity, and Availability. 👁️ **Privileges**: Remote, No Auth needed.…

🔓 **Exploitation Threshold**: **LOW**. 🌐 **Access**: Network Vector (AV:N). 🚫 **Auth**: None required (PR:N). 🤝 **User Interaction**: None (UI:N).…

📂 **Public Exp?**: The `pocs` field is empty. 🕵️‍♂️ **However**, references link to the **GitHub repo** and a **Gist**.…

🔍 **Self-Check**: Scan for **Cannelloni v2.0.0** binaries or processes. 📡 Look for services listening on CAN-related interfaces. Use version detection tools to confirm if you are running the vulnerable release.

🩹 **Official Fix**: The data does not list a specific patch commit. 📝 **Mitigation**: Check the **GitHub repository** (mguentner/cannelloni) for updates.…

🚧 **No Patch?**: **Isolate** the service! 🚫 Block network access to the CAN decoder interface. 🛑 If possible, **disable** the `parseCANFrame` functionality or restrict input to trusted sources only.…

🔥 **Urgency**: **CRITICAL**. 🚨 CVSS is High (H/H/H). Since it’s remote and unauthenticated, patch immediately or isolate. Don’t wait for a PoC to appear—act now to protect your CAN bus infrastructure!
