Summary
Incus is a system container and virtual machine manager. When using an ACL on a device connected to a bridge, Incus version 6.12 and 6.13 generates nftables rules for local services (DHCP, DNS...) that partially bypass security options `security.mac_filtering`, `security.ipv4_filtering` and `security.ipv6_filtering`. This can lead to DHCP pool exhaustion and opens the door for other attacks. A patch is available at commit 2516fb19ad8428454cb4edfe70c0a5f0dc1da214.

"value": "Incus es un contenedor de sistema y administrador de m\u00e1quinas virtuales. Al usar una ACL en un dispositivo conectado a un puente, las versiones 6.12 y 6.13 de Incus generan reglas de nftables para servicios locales (DHCP, DNS, etc.) que omiten parcialmente las opciones de seguridad `security.mac_filtering`, `security.ipv4_filtering` y `security.ipv6_filtering`. Esto puede provocar el agotamiento del pool de DHCP y abrir la puerta a otros ataques. Hay un parche disponible en el commit 2516fb19ad8428454cb4edfe70c0a5f0dc1da214."
