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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2025-52889)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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

  - 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. (CVE-2025-52890)
