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-2026-72308 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-2026-72308/ (Markdown: https://insights.sbomify.com/CVE-2026-72308/index.md)","id":"CVE-2026-72308","markdown":"https://insights.sbomify.com/CVE-2026-72308/index.md","name":"CVE-2026-72308","record":{"aliases":["BELL-CVE-2026-72308","DEBIAN-CVE-2026-72308","GHSA-62qp-mh75-mrwp","UBUNTU-CVE-2026-72308"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A refcount leak in the mlxsw network driver allows local attackers to cause a denial of service by exhausting kernel resources.","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\nmlxsw: fix refcount leak in mlxsw_sp_port_lag_join()\n\nWhen mlxsw_sp_port_lag_index_get() fails, mlxsw_sp_port_lag_join()\nreturns an error without releasing the lag reference obtained by\nthe earlier mlxsw_sp_lag_get().
