CVE-2025-52889 Information

Description

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.
