  3. CVE-2022-48794
In the Linux kernel, the following vulnerability has been resolved: net: ieee802154: at86rf230: Stop leaking skb's Upon error the ieee802154_xmit_complete() helper is not called. Only ieee802154_wake_queue() is called manually. In the Tx case we then leak the skb structure. Free the skb structure upon error before returning when appropriate. As the 'is_tx = 0' cannot be moved in the complete handler because of a possible race between the delay in switching to STATE_RX_AACK_ON and a new interrupt, we introduce an intermediate 'was_tx' boolean just for this purpose. There is no Fixes tag applying here, many changes have been made on this area and the issue kind of always existed.

Summary
  • (es) 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 ejecución entre el retraso en el cambio a STATE_RX_AACK_ON y una nueva interrupción, introducimos un booleano intermedio 'was_tx' solo para este propósito. No se aplica ninguna etiqueta de Correcciones aquí, se han realizado muchos cambios en esta área y el problema siempre existió.
