Description

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

Affected configurations

• linux linux kernel (>= 5.4 < 5.10.249) • linux linux kernel (>= 5.11 < 5.15.199) • linux linux kernel (>= 5.16 < 6.1.162) • linux linux kernel (>= 6.2 < 6.6.122) • linux linux kernel (>= 6.7 < 6.12.67) • linux linux kernel (>= 6.13 < 6.18.7) • linux linux kernel 6.19
