Only\nieee802154_wake_queue() is called manually. In the Tx case we then leak\nthe skb structure.\n\nFree the skb structure upon error before returning when appropriate.\n\nAs the 'is_tx = 0' cannot be moved in the complete handler because of a\npossible race between the delay in switching to STATE_RX_AACK_ON and a\nnew interrupt, we introduce an intermediate 'was_tx' boolean just for\nthis purpose.\n\nThere is no Fixes tag applying here, many changes have been made on this\narea and the issue kind of always existed."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: ieee802154: at86rf230: Detener la fuga de skb. En caso de error, no se llama al asistente ieee802154_xmit_complete(). Solo se llama manualmente a ieee802154_wake_queue(). En el caso de Tx, filtramos la estructura skb. Libere la estructura skb en caso de error antes de regresar cuando sea apropiado. Como 'is_tx = 0' no se puede mover en el controlador completo debido a una posible ejecuci\u00f3n entre el retraso en el cambio a STATE_RX_AACK_ON y una nueva interrupci\u00f3n, introducimos un booleano intermedio 'was_tx' solo para este prop\u00f3sito. No se aplica ninguna etiqueta de Correcciones aqu\u00ed, se han realizado muchos cambios en esta \u00e1rea y el problema siempre existi\u00f3."
