Verification of affected versions, exposure assessment, and prioritization of patching or mitigation are crucial.

  • Temporary interruption of DLP enforcement
  • Potential revelation of per-boot memory layout information to unauthorized users
  • Verification of affected versions and exposure
  • Prioritization of patching or mitigation

Technical summary

The vulnerability affects the Endpoint DLP (EPDLP) service of the Netskope Client, allowing a local standard user to potentially send a specially crafted message that is not properly validated with a bounds check, likely crashing the kernel driver handler. This could temporarily interrupt DLP enforcement and potentially reveal per-boot memory layout information to unauthorized users. Defenders should prioritize verifying affected versions and assessing exposure to prevent potential crashes of the EPDLP service and unauthorized access to memory layout information.

Defensive priority

Defenders should prioritize verifying affected versions and assessing exposure, as the vulnerability could temporarily interrupt DLP enforcement and potentially reveal memory layout information.

Recommended defensive actions

  • Verify affected versions of Netskope Client and Endpoint DLP service
  • Assess exposure and prioritize patching or mitigation
  • Monitor for potential crashes of the EPDLP service
  • Review and update incident response plans
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
