FKIE_CVE-2025-52889

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