CVE-2025-52984

Summary

A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause impact to the availability of the device.

When static route points to a reject next hop and a gNMI query is processed for that static route, rpd crashes and restarts.

This issue affects:

Junos OS:  * all versions before 21.2R3-S9,

  • 21.4 versions before 21.4R3-S10, 
  • 22.2 versions before 22.2R3-S6,
  • 22.4 versions before 22.4R3-S6,
  • 23.2 versions before 23.2R2-S3,
  • 23.4 versions before 23.4R2-S4,
  • 24.2 versions before 24.2R1-S2, 24.2R2;

Junos OS Evolved:

  • all versions before 22.4R3-S7-EVO,
  • 23.2-EVO

versions before 23.2R2-S3-EVO,

  • 23.4-EVO versions before 23.4R2-S4-EVO,
  • 24.2-EVO versions before 24.2R2-EVO.
