Summary
Bluetooth: hci_event: fix potential UAF in SSP passkey handlers
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_event: fix potential UAF in SSP passkey handlers

hci_conn lookup and field access must be covered by hdev lock in hci_user_passkey_notify_evt() and hci_keypress_notify_evt(), otherwise the connection can be freed concurrently.

Extend the hci_dev_lock critical section to cover all conn usage in both handlers.

Keep the existing keypress notification behavior unchanged by routing the early exits through a common unlock path.
