In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: fix chan ref leak in l2cap chan timeout() on !conn
set chan timer() takes a l2cap chan reference via l2cap chan hold()
before scheduling the delayed work. The normal path in
l2cap chan timeout() drops this reference with l2cap chan put() at the
end, but the early return when chan->conn is NULL skips the put,
leaking the reference.
Add the missing l2cap chan put() before the early return.
