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-2026-98434 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-2026-98434/ (Markdown: https://insights.sbomify.com/CVE-2026-98434/index.md)","id":"CVE-2026-98434","markdown":"https://insights.sbomify.com/CVE-2026-98434/index.md","name":"CVE-2026-98434","record":{"aliases":["DEBIAN-CVE-2026-98434","GHSA-62hw-vfc3-fh7q","UBUNTU-CVE-2026-98434"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A missing range check in the Linux kernel sysctl handler allows local attackers to bypass security constraints, potentially leading to privilege escalation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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\nsysctl: Check range in  proc_dointvec_ms_jiffies_minmax\n\nAdd the range check to do_proc_int_conv_ms_jiffies_minmax that commit\nd174174c6776 (\"sysctl: replace SYSCTL_INT_CONV_CUSTOM macro with\nfunctions\") incorrectly removed.","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":"sysctl: Check range in proc_dointvec_ms_jiffies_minmax","id":"CVE-2026-98434","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"EDAC/altera: Use parent device for devres in altr_portb_setup()","id":"CVE-2026-98435"},"packages":[],"prev":{"headline":"KVM: PPC: Book3S HV: fix secure device page leak on uv_page_in() failure","id":"CVE-2026-98433"},"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 range check in the Linux kernel sysctl handler allows local attackers to bypass security constraints, potentially leading to privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-98434/"}
