{"cve":"CVE-2025-52889","nvd":{"published":"2025-06-25T17:15:39.200","modified":"2026-06-17T09:37:13.313","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L","score":3.4},"cwes":["CWE-770"],"references":["https://github.com/lxc/incus/commit/2516fb19ad8428454cb4edfe70c0a5f0dc1da214","https://github.com/lxc/incus/commit/a7c33301738aede3c035063e973b1d885d9bac7c","https://github.com/lxc/incus/security/advisories/GHSA-9q7c-qmhm-jv86","https://github.com/lxc/incus/security/advisories/GHSA-9q7c-qmhm-jv86"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2025-52889","score":0.00254,"percentile":0.16933,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9q7c-qmhm-jv86","url":"https://osv.dev/vulnerability/GHSA-9q7c-qmhm-jv86","summary":"Incus Allocation of Resources Without Limits allows firewall rule bypass on managed bridge networks","modified":"2026-03-30T14:06:03.869502Z","packages":[{"ecosystem":"Go","name":"github.com/lxc/incus/v6","purl":"pkg:golang/github.com/lxc/incus/v6","ranges":["<6.14.0"],"fixed":["6.14.0"]}]},{"id":"GO-2025-3781","url":"https://osv.dev/vulnerability/GO-2025-3781","summary":"Incus Allocation of Resources Without Limits allows firewall rule bypass on managed bridge networks in github.com/lxc/incus","modified":"2026-03-03T04:56:42.361233Z","packages":[{"ecosystem":"Go","name":"github.com/lxc/incus","purl":"pkg:golang/github.com/lxc/incus","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/lxc/incus/v6","purl":"pkg:golang/github.com/lxc/incus/v6","ranges":[">=6.12.0 <6.14.0"],"fixed":["6.14.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
