Vulnerability from github – Published: 2026-04-10 00:30 – Updated: 2026-04-10 00:30

Details

If the authentication packet-type option is configured and a received packet does not match that packet type, the memory leak occurs. When all memory

available to bbe-smgd has been consumed, no new subscribers will be able to login.

The memory utilization of bbe-smgd can be monitored with the following show command:

user@host> show system processes extensive | match bbe-smgd

The below log message can be observed when this limit has been reached:

bbesmgd[]: %DAEMON-3-SMD_DPROF_RSMON_ERROR: Resource unavailability, Reason: Daemon Heap Memory exhaustion

Vulnerability from cvelistv5 – Published: 2026-04-09 21:30 – Updated: 2026-04-09 21:30

Title

Junos OS: MX Series: Mismatch between configured and received packet types causes memory leak in bbe-smgd

Summary

A Missing Release of Memory after Effective Lifetime vulnerability in the BroadBand Edge subscriber management daemon (bbe-smgd) of Juniper Networks Junos OS on MX Series allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS). If the authentication packet-type option is configured and a received packet does not match that packet type, the memory leak occurs. When all memory available to bbe-smgd has been consumed, no new subscribers will be able to login. The memory utilization of bbe-smgd can be monitored with the following show command: user@host> show system processes extensive | match bbe-smgd The below log message can be observed when this limit has been reached: bbesmgd[<PID>]: %DAEMON-3-SMD_DPROF_RSMON_ERROR: Resource unavailability, Reason: Daemon Heap Memory exhaustion This issue affects Junos OS on MX Series: * all versions before 22.4R3-S8, * 23.2 versions before 23.2R2-S5, * 23.4 versions before 23.4R2-S6, * 24.2 versions before 24.2R2-S2, * 24.4 versions before 24.4R2, * 25.2 versions before 25.2R2.
