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-2026-72240 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-2026-72240/ (Markdown: https://insights.sbomify.com/CVE-2026-72240/index.md)","id":"CVE-2026-72240","markdown":"https://insights.sbomify.com/CVE-2026-72240/index.md","name":"CVE-2026-72240","record":{"aliases":["BELL-CVE-2026-72240","DEBIAN-CVE-2026-72240","GHSA-86jq-c78h-58w8","UBUNTU-CVE-2026-72240"],"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":"none","summary":"A reference leak in the SM501 MFD driver can lead to memory exhaustion and denial of service when device registration fails.","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\nmfd: sm501: Fix reference leak on failed device registration\n\nWhen platform_device_register() fails in sm501_register_device(), the\nembedded struct device in pdev has already been initialized by\ndevice_initialize(), but the failure path only reports the error and\nreturns without dropping the device reference for the current platform\ndevice:\n\n  sm501_register_device()\n    -\u003e platform_device_register(pdev)\n       -\u003e device_initialize(\u0026pdev-\u003edev)\n       -\u003e setup_pdev_dma_masks(pdev)\n       -\u003e platform_device_add(pdev)\n\nThis leads to a reference leak when platform_device_register() fails.\nFix this by calling platform_device_put() before returning the error.\n\nThe issue was identified by a static analysis tool I developed and\nconfirmed by manual review.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"mfd: sm501: Fix reference leak on failed device registration","id":"CVE-2026-72240","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"leds: uleds: Fix potential buffer overread","id":"CVE-2026-72241"},"packages":[],"prev":{"headline":"x86/virt/sev: Revert \"Drop WBINVD before setting MSR_AMD64_SYSCFG_SNP_EN\"","id":"CVE-2026-72239"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-17","vendors":["Linux"]},"summary":"A reference leak in the SM501 MFD driver can lead to memory exhaustion and denial of service when device registration fails.","url":"https://insights.sbomify.com/CVE-2026-72240/"}
