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.
