Description

This security bulletin contains information about 1 vulnerability.


1) Use of multiple resources with duplicate identifier (CVE-ID: CVE-2026-57024)

CWE-ID: CWE-694 - Use of Multiple Resources with Duplicate Identifier

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The vulnerability exists due to use of multiple resources with duplicate identifier error in the IKE daemon (iked). A remote non-authenticated attacker can cause a Denial-of-Service (DoS).

On an MX with SPC3 and SRX devices configured for VPN service, when a large number of VPN negotiations fail a peer index rollover will eventually occur.

As a result, new peers are assigned index values that are already in use and the iked process starts to crash repeatedly.
