Descriptions

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nft_flow_offload: reset dst in route object after setting up flow

dst is transferred to the flow object, route object does not own it
anymore. Reset dst in route object, otherwise if flow_offload_add()
fails, error path releases dst twice, leading to a refcount underflow.

En el kernel de Linux, se resolviĆ³ la siguiente vulnerabilidad: netfilter: nft_flow_offload: restablece dst en el objeto de ruta despuĆ©s de configurar el flujo dst se transfiere al objeto de flujo, el objeto de ruta ya no es propietario. Restablezca el dst en el objeto de ruta; de lo contrario, si flow_offload_add() fallo, la ruta de error libera el dst dos veces, lo que provoca un desbordamiento insuficiente del recuento.
