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-2026-68406 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-2026-68406/ (Markdown: https://insights.sbomify.com/CVE-2026-68406/index.md)","id":"CVE-2026-68406","markdown":"https://insights.sbomify.com/CVE-2026-68406/index.md","name":"CVE-2026-68406","record":{"aliases":["BELL-CVE-2026-68406","DEBIAN-CVE-2026-68406","GHSA-4fpv-jc67-f9w9","UBUNTU-CVE-2026-68406"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi","requires_auth":"low_privilege","summary":"A missing validation in the Linux kernel WiFi driver allows local attackers to bypass security checks, potentially leading to privilege escalation or system crashes.","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\nwifi: cfg80211: validate PMSR FTM preamble range\n\nPMSR FTM request parsing accepts preamble values outside the\nenumerated nl80211 preamble range.\n\nReject out-of-range values before using them in the parser capability\nbit test using the policy.\n\n[drop unnecessary check]","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":"wifi: cfg80211: validate PMSR FTM preamble range","id":"CVE-2026-68406","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"wifi: nl80211: free RNR data on MBSSID mismatch","id":"CVE-2026-68407"},"packages":[],"prev":{"headline":"wifi: mac80211: free AP_VLAN bc_buf SKBs outside IRQ lock","id":"CVE-2026-68405"},"products":["Linux"],"published":"2026-08-10","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":"2026-08-19","vendors":["Linux"]},"summary":"A missing validation in the Linux kernel WiFi driver allows local attackers to bypass security checks, potentially leading to privilege escalation or system crashes.","url":"https://insights.sbomify.com/CVE-2026-68406/"}
