*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: ISO: fix refcounting of iso_conn<br /> <br /> iso_conn_del() and iso_chan_del() have a race that results to double-put<br /> of iso_conn:<br /> <br /> [Task hdev-&gt;workqueue] [Task 2]<br /> iso_conn_del iso_chan_del<br /> iso_conn_hold_unless_zero iso_conn_lock<br /> iso_conn_lock conn-&gt;sk = NULL<br /> iso_conn_unlock<br /> sk = iso_sock_hold(conn) conn own refcount when non-NULL, so<br /> iso_conn_del does not need to put it. Adjust the iso_conn_add()<br /> refcounting so that conn is put if it does not get associated with an<br /> sk.
