CVE-2025-52955

An Incorrect Calculation of Buffer Size vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause a memory corruption that leads to a rpd crash. 











When
the logical interface using a routing instance flaps continuously, specific updates are sent to the jflow/sflow modules. This results in memory corruption, leading to an rpd crash and restart. 


Continued receipt of these specific updates will cause a sustained Denial of Service condition.


This issue affects Junos OS:

  *  All versions before 21.2R3-S9, 
  *  All versions of 21.4, 
  *  All versions of 22.2, 
  *  from 22.4 before 22.4R3-S7, 
  *  from 23.2 before 23.2R2-S3, 
  *  from 23.4 before 23.4R2-S4, 
  *  from 24.2 before 24.2R2.


Junos OS Evolved: 



  *  All versions of 21.2-EVO, 
  *  All versions of 21.4-EVO, 
  *  All versions of 22.2-EVO, 
  *  from 22.4 before 22.4R3-S7-EVO, 
  *  from 23.2 before 23.2R2-S3-EVO, 
  *  from 23.4 before 23.4R2-S4-EVO, 
  *  from 24.2 before 24.2R2-EVO.
