FKIE_CVE-2025-52890

Vulnerability from fkie_nvd - Published: 2025-06-25 17:15 - Updated: 2026-06-17 09:37
Severity
8.1 (High) - CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:H
Summary
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.
