CVE-2026-16174
SUMMARY

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.

CVE-2026-16172
SUMMARY

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.
