Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Fix parent socket leak in iso_conn_ready() iso_get_sock() returns the parent socket with a reference held, which is dropped by sock_put() once the child socket has been set up. The error path taken when iso_sock_alloc() fails only calls release_sock() and returns, leaking the reference and thus the parent socket itself. Drop the reference on that path as well.
