As per the scientist who circulated details of the fault – Laurent Gaffié – Microsoft has known regarding the problem for 3 months yet has so far did not repair the weakness.

In case the SMB file sharing procedure error is abused, an assailant would be capable to crash Windows 10 and 8.1 types of machinery, even though presently no statements have been received to indicate the fault might be abused to let distant code performance.

The fault is a memory corruption weakness in the manner that the latest 2 Windows types handle SMB traffic.
