Description OSIDB Bzimport 2026-08-10 12:22:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_sync: hold hdev->lock for hci_conn_params lookups

hci_conn_params_lookup requires hdev->lock be held, otherwise the list
iteration or param access is not safe.

Hold hdev->lock for params lookups in hci_sync.
