Title
Moby's Firewalld reload removes bridge network isolation
Summary
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.

Una vulnerabilidad de firewalld afecta a las versiones de Moby anteriores a la 28.0.0. Al recargarse, Docker no puede recrear las reglas de iptables que a\u00edslan las redes puente, lo que permite que cualquier contenedor acceda a todos los puertos de cualquier otro contenedor a trav\u00e9s de diferentes redes puente en el mismo host. Esto rompe la segmentaci\u00f3n de red entre contenedores que deber\u00edan estar aislados, lo que genera un riesgo significativo en entornos multiusuario. Solo los contenedores en redes internas permanecen protegidos. Las soluciones alternativas incluyen recargar firewalld y reiniciar el daemon de Docker, recrear las redes puente o usar el modo sin root. Los fabricantees prev\u00e9n una soluci\u00f3n para este problema en la versi\u00f3n 25.0.13."

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.\nWorkarounds 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."
