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-2026-72223 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-2026-72223/ (Markdown: https://insights.sbomify.com/CVE-2026-72223/index.md)","id":"CVE-2026-72223","markdown":"https://insights.sbomify.com/CVE-2026-72223/index.md","name":"CVE-2026-72223","record":{"aliases":["BELL-CVE-2026-72223","DEBIAN-CVE-2026-72223","GHSA-pj7h-9r7j-559q","UBUNTU-CVE-2026-72223"],"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":"none","summary":"A memory leak in the Linux kernel's NVDIMM BTT driver allows local attackers to cause denial of service by triggering error paths in arena discovery.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nnvdimm/btt: Free arena sub-allocations on discover_arenas() error path\n\nMemory allocated by btt_freelist_init(), btt_rtt_init(), and\nbtt_maplocks_init() is not freed on some discover_arenas() error\npaths.
