CVE-2026-16172 — Netskope Endpoint DLP Service Out-of-Bounds Read Leading to Process Crash

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.
