CVE-2026-15710
Netskope Client Endpoint DLP Kernel Driver Information Leakage
Description
An information leakage vulnerability exists in the Endpoint DLP component (epdlpdrv.sys) of Netskope Client for Windows prior to version R141. An internal communication channel used by the user-space hook DLL to pass messages through the kernel driver to the daemon lacked proper token-based message validation, allowing local unprivileged processes to send unauthorized queries. Additionally, a reply buffer used by the port message handler was not properly initialized before returning data, leaking residual kernel pool memory from prior allocations. A local unprivileged attacker could exploit this vulnerability to enumerate DLP configuration and feature flags, extract live session tokens, and read kernel memory fragments from other users' operations.
