An attacker positioned within the physical Bluetooth transmission range can exploit this flaw by sending specifically crafted Bluetooth requests to the target device. Because the bluez daemon often operates with elevated privileges, successful exploitation grants the attacker administrative control over the underlying Linux host. This issue affects various Linux distributions utilizing the BlueZ stack and poses a significant risk to mobile devices, workstations, and IoT hardware that maintain persistent Bluetooth connectivity. Defenders should prioritize patching BlueZ to the latest version and, where feasible, disable Bluetooth services on sensitive systems until updates are applied.

Impact

The vulnerability allows for full system compromise, enabling attackers to gain unauthorized access to data, install persistence mechanisms, or move laterally within a local network. It impacts a wide range of Linux-based devices, including workstations, mobile platforms, and embedded IoT systems that rely on the BlueZ stack for Bluetooth communication.

Recommendation

  • Update the BlueZ package to the latest version provided by your Linux distribution to address CVE-2024-27305.
  • Audit systems for active Bluetooth services and disable the bluetoothd service on servers or high-security endpoints where Bluetooth is not a required functional component.
  • Use host-based firewall rules to restrict Bluetooth-related traffic where possible, although this does not mitigate the proximity-based nature of the attack.
