CVE-2025-52958

A Reachable Assertion vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS).On all Junos OS and Junos OS Evolved devices, when route validation is enabled, a rare condition during BGP initial session establishment can lead to an rpd crash and restart. This occurs specifically when the connection request fails during error-handling scenario.

Continued session establishment failures leads to a sustained DoS condition.

  • All versions before 22.2R3-S6,
  • from 22.4 before 22.4R3-S6,
  • from 23.2 before 23.2R2-S3,
  • from 23.4 before 23.4R2-S4,
  • from 24.2 before 24.2R2;
