CVE-2025-52890
CVE-2025-52890 · Incus vulnerable to antispoofing nftables firewall rule bypass on bridge networks with ACLs
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Incus is a system container and virtual machine manager. When using an ACL on a device connected to a bridge, Incus versions 6.12 and 6.13generates nftables rules that partially bypass security options `security.mac_filtering`, `security.ipv4_filtering` and `security.ipv6_filtering`. This can lead to ARP spoofing on the bridge and to fully spoof another VM/container on the same bridge. Commit 254dfd2483ab8de39b47c2258b7f1cf0759231c8 contains a patch for the issue.
