OK thanks for your help, here is the FILE-ID: DLG3X
filename : 20170901_0924_DLG3X_688137174.zip

We had contact with the provider of the driver used in our product (WinDivert). It seems that the problem occurs with several Antivirus, all are using requests interception by a web agent.

The problem seems to be link to a double-free of the NET_BUFFER_LIST

Is there any way to have a direct contact with the technical team ?

Regards
