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.
