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-2026-31459 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-31459/ (Markdown: https://insights.sbomify.com/CVE-2026-31459/index.md)","id":"CVE-2026-31459","markdown":"https://insights.sbomify.com/CVE-2026-31459/index.md","name":"CVE-2026-31459","record":{"aliases":["BELL-CVE-2026-31459","DEBIAN-CVE-2026-31459","GHSA-6c8g-q98p-w229","UBUNTU-CVE-2026-31459"],"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 memory leak in the Linux kernel DAMON sysfs interface can lead to resource exhaustion and denial of service under specific failure conditions.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmm/damon/sysfs: fix param_ctx leak on damon_sysfs_new_test_ctx() failure\n\nPatch series \"mm/damon/sysfs: fix memory leak and NULL dereference\nissues\", v4.\n\nDAMON_SYSFS can leak memory under allocation failure, and do NULL pointer\ndereference when a privileged user make wrong sequences of control.
