It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72128 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-72128/ (Markdown: https://insights.sbomify.com/CVE-2026-72128/index.md)","id":"CVE-2026-72128","markdown":"https://insights.sbomify.com/CVE-2026-72128/index.md","name":"CVE-2026-72128","record":{"aliases":["BELL-CVE-2026-72128","DEBIAN-CVE-2026-72128","GHSA-qr86-v236-8g77","UBUNTU-CVE-2026-72128"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A refcount leak in the Linux kernel NVMe target driver allows local attackers to cause resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnvmet: fix refcount leak in nvmet_sq_create()\n\nIn nvmet_sq_create(), a reference on the ctrl is taken\nvia kref_get_unless_zero() before calling nvmet_check_sqid().\nIf nvmet_check_sqid() fails, the function returns the error\ndirectly without releasing the reference, leading to a leak.\n\nFix this by jumping to the \"ctrl_put\" label, which already\nperforms the necessary nvmet_ctrl_put(ctrl).
