Vulnerability from github – Published: 2025-07-11 18:30 – Updated: 2025-07-11 18:30

Details

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,
22.4 versions before 22.4R3-S7,
23.2 versions before 23.2R2-S4,
23.4 versions before 23.4R2-S4,
24.2 versions before 24.2R2,
24.4 versions before 24.4R1-S2, 24.4R2;

Junos OS Evolved:

all versions before 22.2R3-S7-EVO
22.4-EVO versions before 22.4R3-S7-EVO,
23.2-EVO versions before 23.2R2-S4-EVO,
23.4-EVO versions before 23.4R2-S4-EVO,
24.2-EVO versions before 24.2R2-EVO,

CVE-2025-52986 (GCVE-0-2025-52986)

Vulnerability from cvelistv5 – Published: 2025-07-11 15:10 – Updated: 2025-07-15 19:55

Title

Junos OS and Junos OS Evolved: When RIB sharding is configured each time a show command is executed RPD memory leaks

Summary

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, * 22.4 versions before 22.4R3-S7, * 23.2 versions before 23.2R2-S4, * 23.4 versions before 23.4R2-S4, * 24.2 versions before 24.2R2, * 24.4 versions before 24.4R1-S2, 24.4R2; Junos OS Evolved: * all versions before 22.2R3-S7-EVO * 22.4-EVO versions before 22.4R3-S7-EVO, * 23.2-EVO versions before 23.2R2-S4-EVO, * 23.4-EVO versions before 23.4R2-S4-EVO, * 24.2-EVO versions before 24.2R2-EVO, * 24.4-EVO versions before 24.4R2-EVO.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
