## What is CVE-2026-16174?

CVE-2026-16174 is a high-severity vulnerability in Netskope Endpoint DLP, published on 10 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Netskope was notified about a potential gap in Netskope Endpoint DLP (EPDLP) running on Windows systems. Successful exploitation of the gap could potentially allow a privileged user to send a crafted message to the EPDLP process port to trigger an integer overflow, leading to memory corruption. Successful exploitation would require the EPDLP module to be enabled in the client configuration, and that Memory Integrity is disabled. A successful exploit could potentially result in a denial-of-service, arbitrary code execution, or privilege escalation on the local machine.

Weakness: CWE-190 (Integer Overflow or Wraparound)
