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-2025-40116 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-2025-40116/ (Markdown: https://insights.sbomify.com/CVE-2025-40116/index.md)","id":"CVE-2025-40116","markdown":"https://insights.sbomify.com/CVE-2025-40116/index.md","name":"CVE-2025-40116","record":{"aliases":["BELL-CVE-2025-40116","DEBIAN-CVE-2025-40116","GHSA-pp9h-36fp-569w","ROOT-OS-DEBIAN-11-CVE-2025-40116","ROOT-OS-DEBIAN-13-CVE-2025-40116","ROOT-OS-UBUNTU-2404-CVE-2025-40116","UBUNTU-CVE-2025-40116"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel's max3421 USB host driver can cause a system crash during probe cleanup.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nusb: host: max3421-hcd: Fix error pointer dereference in probe cleanup\n\nThe kthread_run() function returns error pointers so the\nmax3421_hcd-\u003espi_thread pointer can be either error pointers or NULL.\nCheck for both before dereferencing it.","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":"usb: host: max3421-hcd: Fix error pointer dereference in probe cleanup","id":"CVE-2025-40116","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":8,"next":{"headline":"misc: pci_endpoint_test: Fix array underflow in pci_endpoint_test_ioctl()","id":"CVE-2025-40117"},"packages":[],"prev":{"headline":"scsi: mpt3sas: Fix crash in transport port remove by using ioc_info()","id":"CVE-2025-40115"},"products":["Linux"],"published":"2025-11-12","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":"2026-05-11","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel's max3421 USB host driver can cause a system crash during probe cleanup.","url":"https://insights.sbomify.com/CVE-2025-40116/"}
