## What is CVE-2026-16172?

CVE-2026-16172 is a medium-severity memory corruption 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 of an out-of-bounds heap read affecting the Endpoint DLP (EPDLP) service of the Netskope Client. A local standard user could potentially send a specially crafted message that is not properly validated with a bounds check, likely crashing the kernel driver handler. Successful exploitation could potentially crash the EPDLP service, temporarily interrupting DLP enforcement. A successful exploit could potentially also reveal per-boot memory layout information to unauthorized users.

Weakness: CWE-125 (Out-of-bounds Read)
