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-2026-98583 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-2026-98583/ (Markdown: https://insights.sbomify.com/CVE-2026-98583/index.md)","id":"CVE-2026-98583","markdown":"https://insights.sbomify.com/CVE-2026-98583/index.md","name":"CVE-2026-98583","record":{"aliases":["AZL-108783","BELL-CVE-2026-98583","DEBIAN-CVE-2026-98583","GHSA-fgwh-2g3x-83j6","UBUNTU-CVE-2026-98583"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel NFC driver","requires_auth":"none","summary":"A missing length check in the Linux kernel NFC driver allows attackers to cause a denial of service via malformed packets.","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\nnfc: nfcmrvl: validate helper command length before pull\n\nThe firmware download receive path removes the NCI data header and\nreads the helper command before validating the remaining packet length.\nA short frame can therefore reach the data access before the malformed\npacket is rejected.\n\nValidate the complete helper command length before stripping the NCI\ndata header.","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":"nfc: nfcmrvl: validate helper command length before pull","id":"CVE-2026-98583","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"net/sched: fix potential stack infoleak in em_text_dump()","id":"CVE-2026-98584"},"packages":[],"prev":{"headline":"nfc: st21nfca: validate received frame size","id":"CVE-2026-98582"},"products":["Linux"],"published":"2026-10-18","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":"2026-10-19","vendors":["Linux"]},"summary":"A missing length check in the Linux kernel NFC driver allows attackers to cause a denial of service via malformed packets.","url":"https://insights.sbomify.com/CVE-2026-98583/"}
