kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...
