                            Description
                            Netskope is notified about a potential gap in its agent (NS Client) in which a malicious actor could trigger a memory leak by sending a crafted DNS packet to a machine. A successful exploitation may require administrative privileges on the machine, based on the exact configuration. A successful exploit can potentially result in user-controllable memory being leaked in a domain name stored on the local machine.
