Name of the Vulnerable Software and Affected Versions: McAfee Data Loss Prevention (DLP) Endpoint for Windows versions prior to 11.6.100

Description: A Denial of Service issue allows a local, low privileged, attacker to cause a BSoD through suspending a process, modifying the process's memory and restarting it. This is triggered by the hdlphook driver reading invalid memory.

Recommendations: For versions prior to 11.6.100, update to version 11.6.100 or later to resolve the issue. As a temporary workaround, consider restricting access to the hdlphook driver to minimize the risk of exploitation.
