CVE-2025-52986

A Missing Release of Memory after Effective Lifetime vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low privileged user to cause an impact to the availability of the device.

When RIB sharding is enabled and a user executes one of several routing related 'show' commands, a certain amount of memory is leaked. When all available memory has been consumed rpd will crash and restart.

The leak can be monitored with the CLI command:



show task memory detail | match task_shard_mgmt_cookie



where the allocated memory in bytes can be seen to continuously increase with each exploitation.



This issue affects:

Junos OS:

  *  all versions before 21.2R3-S9,
  *  21.4 versions before 21.4R3-S11,
  *  22.2 versions before 22.2R3-S7,

CWE-401 Missing Release of Memory after Effective Lifetime

The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.
