CVE-2025-52952
An Out-of-bounds Write vulnerability in the connectivity fault management (CFM) daemon of Juniper Networks Junos OS on MX Series with MPC-BUILTIN, MPC1 through MPC9 line cards allows an unauthenticated adjacent attacker to send a malformed packet to the device, leading to an FPC crash and restart, resulting in a Denial of Service (DoS).
Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.
This issue affects Juniper Networks:
Junos OS:
* All versions before 22.2R3-S1,
* from 22.4 before 22.4R2.
This feature is not enabled by default.
