In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: iso: Fix circular lock in iso_conn_big_sync
This fixes the circular locking dependency warning below, by reworking
iso_sock_recvmsg, to ensure that the socket lock is always released
before calling a function that locks hdev.
