"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix missing locking causing hanging calls\n\nIf a call gets aborted (e.g. because kafs saw a signal) between it being\nqueued for connection and the I/O thread picking up the call, the abort\nwill be prioritised over the connection and it will be removed from\nlocal->new_client_calls by rxrpc_disconnect_client_call() without a lock\nbeing held. This may cause other calls on the list to disappear if a race\noccurs.\n\nFix this by taking the client_call_lock when removing a call from whatever\nlist its ->wait_link happens to be on."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rxrpc: Se corrige la falta de bloqueo que causa llamadas colgadas Si una llamada se cancela (por ejemplo, porque kafs vio una se\u00f1al) entre su puesta en cola para la conexi\u00f3n y el hilo de E/S que recoge la llamada, la cancelaci\u00f3n tendr\u00e1 prioridad sobre la conexi\u00f3n y se eliminar\u00e1 de local->new_client_calls mediante rxrpc_disconnect_client_call() sin que se mantenga un bloqueo. Esto puede provocar que otras llamadas de la lista desaparezcan si se produce una ejecuci\u00f3n. Arregle esto tomando el client_call_lock al eliminar una llamada de cualquier lista en la que se encuentre su ->wait_link."
