What it actually does
Double registration of the suspend notifier during hci_register_dev for fake CSR 5.0 Bluetooth controllers triggers a kernel panic via blocking_notifier_chain_register in btusb_probe.
Why it matters to the business
Linux systems using affected Bluetooth hardware experience sudden kernel crashes and reboots when fake controllers are reconnected, causing unplanned downtime and loss of Bluetooth functionality until reboot.
How an attack unfolds
An attacker with physical access prepares a fake CSR 5.0 clone controller and repeatedly plugs it into a vulnerable Linux system; the btusb driver registers the suspend notifier twice, leading to the panic shown in the call trace during usb_new_device and hub_event processing.
How to fix it
Apply the upstream fix that prevents duplicate suspend notifier registration in hci_register_dev; rebuild and deploy the patched kernel. Monitor for any downstream package updates that include commit 3c551261d0e230635774798009951fa83a07cc3a equivalents where applicable.
How to confirm the fix worked
Confirm the patched kernel no longer calls blocking_notifier_chain_register twice on replug; reproduce the scenario with a CSR clone and verify absence of the -17 probe error and panic trace.
Typical attack path
- Locate a Linux host with the vulnerable bluetooth and btusb modules
- Obtain or emulate a fake CSR 5.0 controller
- Insert the device to trigger initial probe
- Remove and replug the device to force second hci_register_dev call
- Trigger kernel panic and denial of service
How to detect it
Search kernel logs for the exact panic trace involving blocking_notifier_chain_register and hci_register_dev, or btusb probe failures returning error -17; inspect dmesg and journalctl for repeated usb_probe_device events on the same device path.
- blocking_notifier_chain_register+0x33/0x60
- hci_register_dev+0x316/0x3d0
- btusb_probe+0x979/0xd85
- probe of .* failed with error -17
What your security team should do
- Prioritize kernel updates on all systems exposing Bluetooth to untrusted controllers
- Disable Bluetooth when not required via kernel configuration or runtime blacklisting
- Add monitoring for kernel panics containing btusb_probe or hci_register_dev symbols
