Doc Text:	A use-after-free vulnerability was found in the Linux kernel's Bluetooth SCO. When sco_sock_timeout() is called, conn->sk may be unlinked/freed while waiting for sco_conn_lock. This checks if the conn->sk is still valid by checking if it is part of sco_sk_list, leading to a loss of availability and system confidentiality.	Story Points:	---
