=========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2026.3393 K000160663: Moby vulnerability CVE-2025-54410 9 April 2026 =========================================================================== AUSCERT Security Bulletin Summary --------------------------------- Product: BIG-IP Next CNF BIG-IP Next for Kubernetes BIG-IP Next SPK Publisher: F5 Networks Operating System: F5 Resolution: None CVE Names: CVE-2025-54410 Original Bulletin: https://my.f5.com/manage/s/article/K000160663 Comment: CVSS (Max): 3.3 CVE-2025-54410 (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N) CVSS Source: F5 Networks Calculator: https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N EPSS (Max): 0.0% (0th) CVE-2025-54410 2026-04-08 - --------------------------BEGIN INCLUDED TEXT-------------------- K000160663: Moby vulnerability CVE-2025-54410 Published Date: Apr 8, 2026 Security Advisory Description Moby is an open source container framework developed by Docker Inc. that is distributed as Docker Engine, Mirantis Container Runtime, and various other downstream projects/products. A firewalld vulnerability affects Moby releases before 28.0.0. When firewalld reloads, Docker fails to re-create iptables rules that isolate bridge networks, allowing any container to access all ports on any other container across different bridge networks on the same host. This breaks network segmentation between containers that should be isolated, creating significant risk in multi-tenant environments. Only containers in --internal networks remain protected. Workarounds include reloading firewalld and either restarting the docker daemon, re-creating bridge networks, or using rootless mode. Maintainers anticipate a fix for this issue in version 25.0.13. ( CVE-2025-54410) Impact This vulnerability can lead to sensitive data exposure or unintended program flows that trigger denial-of-service (DoS) conditions or system process termination. Security Advisory Status F5 Product Development has assigned ID 2009629, 2068713, 2070689, and 2138361 (BIG-IP SPK, BIG-IP CNF, and BIG-IP Next for Kubernetes) to this vulnerability. To determine if your product and version have been evaluated for this vulnerability, refer to the Evaluated products box. To determine if your release is known to be vulnerable, the components or features that are affected by the vulnerability, and for information about releases, point releases, or hotfixes that address the vulnerability, refer to the following tables. You can also use iHealth to diagnose a vulnerability for BIG-IP, BIG-IQ, and F5OS systems. For more information about using iHealth, refer to K27404821: Using F5 iHealth to diagnose vulnerabilities. For more information about security advisory versioning, refer to K51812227: Understanding security advisory versioning. In this section o BIG-IP Next o BIG-IP and BIG-IQ o F5 Distributed Cloud and NGINX Services o F5OS o NGINX o Other products BIG-IP Next Note: After F5 releases a fix for a given branch, that fix applies to all subsequent minor, maintenance, and point releases for that branch; F5 will not list additional fixes for that branch in the table. For example, when F5 releases a fix in BIG-IP Next SPK 2.0.1, the fix also applies to 2.0.2 and all later 2.0.x releases.

Security Advisory Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by installing a version listed in the Fixes introduced in column. If the Fixes introduced in column does not list a version for your branch, then no update candidate currently exists for that branch and F5 recommends that you upgrade to a version with the fix (refer to the tables). If the Fixes introduced in column lists a version prior to the one you are running, in the same branch, then your version should have the fix.
