CVE-2024-2105
📋 TL;DR
This vulnerability allows an unauthorized attacker within Bluetooth range to send specially crafted BLE connection requests that cause improper validation, leading to a deadlock condition in affected devices. The attack requires proximity to the target device and affects systems with vulnerable Bluetooth implementations.
💻 Affected Systems
- HARMAN automotive systems with vulnerable BLE implementations
