{"id":"UBUNTU-CVE-2025-52889","details":"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.","modified":"2026-07-02T18:01:29.038506883Z","published":"2025-06-25T17:15:00Z","upstream":["CVE-2025-52889"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-52889"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-52889"},{"type":"REPORT","url":"https://github.com/lxc/incus/commit/2516fb19ad8428454cb4edfe70c0a5f0dc1da214"},{"type":"REPORT","url":"https://github.com/lxc/incus/commit/a7c33301738aede3c035063e973b1d885d9bac7c"},{"type":"REPORT","url":"https://github.com/lxc/incus/security/advisories/GHSA-9q7c-qmhm-jv86"}],"affected":[{"package":{"name":"incus","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/incus?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.4-1ubuntu1","0.5.1-1","0.5.1-3","0.6-1","6.0.0-1","6.0.0-1ubuntu0.1","6.0.0-1ubuntu0.2","6.0.0-1ubuntu0.2+esm1","6.0.0-1ubuntu0.3","6.0.0-1ubuntu0.3+esm1","6.0.0-1ubuntu0.3+esm2","6.0.0-1ubuntu0.3+esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"6.0.0-1ubuntu0.3+esm3","binary_name":"golang-github-lxc-incus-dev"},{"binary_name":"incus","binary_version":"6.0.0-1ubuntu0.3+esm3"},{"binary_name":"incus-agent","binary_version":"6.0.0-1ubuntu0.3+esm3"},{"binary_name":"incus-client","binary_version":"6.0.0-1ubuntu0.3+esm3"},{"binary_version":"6.0.0-1ubuntu0.3+esm3","binary_name":"incus-migrate"},{"binary_name":"incus-tools","binary_version":"6.0.0-1ubuntu0.3+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-52889.json"}},{"package":{"name":"incus","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/incus?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.3-4","6.0.4-2"],"ecosystem_specific":{"binaries":[{"binary_version":"6.0.4-2","binary_name":"golang-github-lxc-incus-dev"},{"binary_name":"incus","binary_version":"6.0.4-2"},{"binary_name":"incus-agent","binary_version":"6.0.4-2"},{"binary_version":"6.0.4-2","binary_name":"incus-base"},{"binary_name":"incus-client","binary_version":"6.0.4-2"},{"binary_version":"6.0.4-2","binary_name":"incus-extra"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-52889.json"}},{"package":{"name":"incus","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/incus?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.0.4-2","6.0.5-8","6.0.5-8ubuntu0.26.04.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"golang-github-lxc-incus-dev","binary_version":"6.0.5-8ubuntu0.26.04.1~esm1"},{"binary_version":"6.0.5-8ubuntu0.26.04.1~esm1","binary_name":"incus"},{"binary_name":"incus-agent","binary_version":"6.0.5-8ubuntu0.26.04.1~esm1"},{"binary_name":"incus-base","binary_version":"6.0.5-8ubuntu0.26.04.1~esm1"},{"binary_name":"incus-client","binary_version":"6.0.5-8ubuntu0.26.04.1~esm1"},{"binary_name":"incus-extra","binary_version":"6.0.5-8ubuntu0.26.04.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-52889.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L"},{"type":"Ubuntu","score":"medium"}]}
