  2. Vulnerabilities (CVE)
  3. CVE-2025-30647
A Missing Release of Memory after Effective Lifetime vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on MX Series allows an unauthenticated adjacent attacker to cause a Denial-of-Service (DoS). In a subscriber management scenario, login/logout activity triggers a memory leak, and the leaked memory gradually increments and eventually results in a crash.                 user@host> show chassis fpc                                        Temp    CPU Utilization (%)   CPU Utilization (%)   Memory     Utilization (%)                       Slot State       (C)     Total   Interrupt     1min   5min  15min    DRAM (MB)  Heap   Buffer                       2 Online         36       10         0          9     8     9        32768      26         0                                                                                                       This issue affects Junos OS on MX Series: * All versions before 21.2R3-S9 * from 21.4 before 21.4R3-S10 * from 22.2 before 22.2R3-S6 * from 22.4 before 22.4R3-S5 * from 23.2 before 23.2R2-S3 * from 23.4 before 23.4R2-S3 * from 24.2 before 24.2R2.

Summary
  • (es) Una vulnerabilidad de falta de liberación de memoria tras el tiempo de vida útil efectivo en el motor de reenvío de paquetes (PFE) de Juniper Networks Junos OS en la serie MX permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). En un escenario de gestión de suscriptores, la actividad de inicio y cierre de sesión desencadena una fuga de memoria, que aumenta gradualmente y finalmente provoca un bloqueo. ???????????user@host> show chassis fpc ???????????????????????????????????????Temp ??
