In the Linux kernel, the following vulnerability has been resolved: can: j1939: prevent deadlock by moving j1939skerrqueue() This commit addresses a deadlock situation that can occur in certain scenarios, such as when running data TP/ETP transfer and subscribing to the error queue while receiving a net down event. The deadlock involves locks in the following order: 3 j1939sessionlistlock -> activesessionlistlock j1939sessionactivate ... j1939skqueueactivatenext -> sksessionqueuelock ... j1939xtprxeomaone 2 j1939skqueuedropall -> sksessionqueuelock ... j1939sknetdeveventnetdown -> j1939sockslock j1939netdevnotify 1 j1939skerrqueue -> j1939sockslock _j1939sessioncancel -> activesessionlistlock j1939tprxtimer CPU0 CPU1 ---- ---- lock(&priv->activesessionlistlock); lock(&jsk->sksessionqueuelock); lock(&priv->activesessionlistlock); lock(&priv->j1939sockslock); The solution implemented in this commit is to move the j1939skerrqueue() call out of the activesessionlistlock context, thus preventing the deadlock situation.
