Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-41648 exists.\n\nAffected packages and fixed versions:\n- github.com/lxc/incus/v6/cmd/incusd (Go): affected all versions up to 6.23.0; no fix listed\n- github.com/lxc/incus/v6/cmd/incusd (Go): affected all versions up to 6.23.0; no fix listed\n- github.com/lxc/incus (Go): affected all versions; no fix listed\n- github.com/lxc/incus/v6 (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-2026-41648/ (Markdown: https://insights.sbomify.com/CVE-2026-41648/index.md)","id":"CVE-2026-41648","markdown":"https://insights.sbomify.com/CVE-2026-41648/index.md","name":"CVE-2026-41648","record":{"aliases":["DEBIAN-CVE-2026-41648","GHSA-67wx-r9xr-x75x","GO-2026-5168","UBUNTU-CVE-2026-41648"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Incus container manager","requires_auth":"low_privilege","summary":"An authenticated user can cause a denial of service by uploading a crafted image or backup tarball with unbounded YAML metadata.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"incus","vendor":"linuxcontainers"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Incus is a system container and virtual machine manager.
