Endpoint DLP Module Out-of-Bounds Read Vulnerability
CVE-2026-2810 April 29, 2026
If you’ve ever trusted your endpoint agent too much, this one might make you raise an eyebrow. CVE-2026-2810 affects Netskope’s Endpoint DLP module on Windows, where an out-of-bounds read can be triggered by a local, unprivileged user.
The exploit path is pretty straightforward in security terms but still dangerous in real operations. A user triggers improper memory access within the driver, causing the system to crash into the dreaded Blue Screen of Death. That’s not just annoying. For organizations relying on continuous endpoint enforcement, that’s effectively a denial-of-service on the control layer.
The catch here is configuration. The Endpoint DLP module must be enabled. Sounds normal, right? But that’s exactly what many organizations do to enforce data protection. So yes, the feature meant to protect data becomes the attack surface. Classic.
From a remediation standpoint, Netskope has already addressed this issue in newer client releases. You’ll want to prioritize upgrading affected clients to versions at or beyond the fixed releases listed in the advisory. You can refer to official guidance here:

Hardening recommendations from Netskope also emphasize tightening tenant configurations and applying secure deployment practices:

Best practices moving forward
Keep endpoint agents updated like your life depends on it
Monitor endpoint crashes as potential security signals, not just IT noise
Limit unnecessary local privileges across endpoints
End-user responsibilities
Avoid installing or running untrusted tools that might interact with system drivers
Report repeated system crashes instead of ignoring them
Stay compliant with endpoint security policies, especially those involving DLP agents
In short, this vulnerability reminds us that even security controls need security controls.
