In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: clear iso_data always when detaching conn from hcon When setting conn->hcon = NULL, also conn->hcon->iso_data = NULL is necessary, otherwise later iso_conn_free() will UAF. Fix clearing of iso_data in iso_sock_disconn() Fixes KASAN: slab-use-after-free in iso_conn_hold_unless_zero on iso_sock_release() followed by hci_abort_conn_sync().
