Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: can: j1939: j1939_xtp_rx_rts_session_active(): deactivate session upon receiving the second rts<br />
<br />
Since j1939_session_deactivate_activate_next() in j1939_tp_rxtimer() is<br />
called only when the timer is enabled, we need to call<br />
j1939_session_deactivate_activate_next() if we cancelled the timer.<br />
Otherwise, refcount for j1939_session leaks, which will later appear as<br />
<br />
| unregister_netdevice: waiting for vcan0 to become free. Usage count = 2.<br />
<br />
problem.
