⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing remote code execution, data exfiltration, or device takeover
Likely Case
Unauthorized access to device functionality, potential data manipulation, or service disruption
If Mitigated
Limited impact if network segmentation and strict access controls prevent packet delivery
🎯 Exploit Status
Proof-of-concept available on GitHub demonstrates packet crafting; exploitation requires network access to device
