  "details": "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-\u003econn is NULL skips the put, leaking the reference.  Add the missing l2cap_chan_put() before the early return.",
