CVE-2025-15584
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNetskope was notified about a potential gap in its Endpoint DLP Module for Netskope Client on Windows systems. The successful exploitation of the gap can potentially allow an unprivileged user to trigger an integer overflow within the filter communication port, leading to a Blue-Screen-of-Death (BSOD). Successful exploitation would require the Endpoint DLP module to be enabled in the client configuration. A successful exploit can potentially result in a denial-of-service for the local machine.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAn integer overflow vulnerability exists in the filter communication port of the Netskope Endpoint DLP Module for Windows. An unprivileged local user can trigger this overflow, causing a Blue-Screen-of-Death (BSOD) and resulting in local denial-of-service. Exploitation requires the Endpoint DLP module to be enabled in the client configuration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Netskope Endpoint Agent is installedCheck for Netskope client installation by reviewing installed programs in Windows Settings > Apps & Features, or query the registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'Netskope'Affected if Netskope Endpoint Agent is found on the system
-
Confirm Endpoint DLP module is enabledOpen Netskope Client UI and navigate to the DLP settings or policy configuration, or inspect the client configuration file (typically stored in %ProgramData%\Netskope\ or %AppData%\Netskope\) for DLP-related settingsAffected if Endpoint DLP module status shows as enabled or the configuration contains DLP policy rules active
-
Check Netskope client versionIn Netskope Client UI, go to About or Help > About, or check the executable version of the Netskope agent binary in the installation directoryAffected if Installed version falls within the affected range and cannot be determined from available information - assume affected if DLP is enabled
-
Identify filter communication port activityUse netstat or TCPView to observe network activity on ports associated with Netskope DLP filter driver (check for listening ports or active connections from netskope related processes)Affected if Filter communication port is active and DLP module is enabled
The environment is affected if Netskope Endpoint DLP Module is installed AND the Endpoint DLP feature is enabled in the client configuration, as exploitation requires the DLP module to be active.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataDisable the Endpoint DLP module in the Netskope Client configuration if not required for business operations, as a temporary mitigation until vendor-supplied patches are applied.
