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-2026-80574 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-2026-80574/ (Markdown: https://insights.sbomify.com/CVE-2026-80574/index.md)","id":"CVE-2026-80574","markdown":"https://insights.sbomify.com/CVE-2026-80574/index.md","name":"CVE-2026-80574","record":{"aliases":["AZL-97839","BELL-CVE-2026-80574","DEBIAN-CVE-2026-80574","GHSA-qm8h-24xg-3v98","UBUNTU-CVE-2026-80574"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"An out-of-bounds write in the Focaltech input driver allows attackers to corrupt memory, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nInput: focaltech - fix array out-of-bounds in focaltech_process_rel_packet\n\nMake finger2 (and also finger1) unsigned, so that if the finger index in\nthe packet is 0 then subtracting 1 creates an array index which overflows\nabove the existing check for FOC_MAX_FINGERS, as the existing comment says\nit should, instead of writing to state-\u003efingers[-1].","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":"Input: focaltech - fix array out-of-bounds in focaltech_process_rel_packet","id":"CVE-2026-80574","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":"Input: cs40l50-vibra - validate custom data from user space","id":"CVE-2026-80575"},"packages":[],"prev":{"headline":"Input: iforce - validate input packet lengths","id":"CVE-2026-80573"},"products":["Linux"],"published":"2026-08-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"An out-of-bounds write in the Focaltech input driver allows attackers to corrupt memory, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-80574/"}
