Description
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: mgmt: fix locking in unpair_device/disconnect_sync
Dereferencing RCU-protected pointers outside critical sections is
invalid and may lead to UAF.
Take hdev->lock for hci_conn lookup and hci_abort_conn(). Don't use RCU
to ensure the conn is fully initialized at this point.
