Summary

Netskope was notified about a potential gap in its agent (NS Client) on Windows systems. If this gap is successfully exploited, a local, authenticated user with Administrator privileges can improperly load the driver as a generic kernel service. This triggers the flaw, causing a system crash (Blue-Screen-of-Death) and resulting in a Denial of Service (DoS) for the affected machine.
