CVE-2025-30651

Media report

A Buffer Access with Incorrect Length Value vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
When an attacker sends a specific ICMPv6 packet to an interface with "protocols router-advertisement" configured, rpd crashes and restarts. Continued receipt of this packet will cause a sustained DoS condition. 




This issue only affects systems configured with IPv6.

  *  from 21.4 before 21.4R3-S10,

CWE-805 Buffer Access with Incorrect Length Value

The product uses a sequential operation to read or write a buffer, but it uses an incorrect length value that causes it to access memory that is outside of the bounds of the buffer.
