It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-52889 exists.\n\nAffected packages and fixed versions:\n- github.com/lxc/incus/v6 (Go): affected all versions; fixed in 6.14.0\n- github.com/lxc/incus/v6 (Go): affected all versions; fixed in 6.14.0\n- github.com/lxc/incus/v6 (Go): affected from 6.12.0; fixed in 6.14.0\n- github.com/lxc/incus (Go): affected all versions; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-52889/ (Markdown: https://insights.sbomify.com/CVE-2025-52889/index.md)","id":"CVE-2025-52889","markdown":"https://insights.sbomify.com/CVE-2025-52889/index.md","name":"CVE-2025-52889","record":{"aliases":["GHSA-9q7c-qmhm-jv86","GO-2025-3781","UBUNTU-CVE-2025-52889"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Incus container manager","requires_auth":"high_privilege","summary":"Attackers can bypass firewall filtering to exhaust DHCP pools, causing denial of service in Incus environments using bridge networks with ACLs.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":3.4,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"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.
