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-2026-72114 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-2026-72114/ (Markdown: https://insights.sbomify.com/CVE-2026-72114/index.md)","id":"CVE-2026-72114","markdown":"https://insights.sbomify.com/CVE-2026-72114/index.md","name":"CVE-2026-72114","record":{"aliases":["BELL-CVE-2026-72114","DEBIAN-CVE-2026-72114","GHSA-fxhv-rjvf-632g","UBUNTU-CVE-2026-72114"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel CAN","requires_auth":"low_privilege","summary":"A missing length validation in the Linux kernel CAN BCM module allows attackers to cause a denial of service via malformed RTR replies.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/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\ncan: bcm: validate frame length in bcm_rx_setup() for RTR replies\n\nbcm_tx_setup() validates cf-\u003elen against the CAN/CAN FD DLC limits\nbefore installing frames for TX_SETUP, but bcm_rx_setup() never did\nthe same for the RTR-reply frame configured via RX_SETUP with\nRX_RTR_FRAME.","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":"can: bcm: validate frame length in bcm_rx_setup() for RTR replies","id":"CVE-2026-72114","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":"can: bcm: track a single source interface for ANYDEV timeout/throttle ops","id":"CVE-2026-72115"},"packages":[],"prev":{"headline":"can: bcm: add missing device refcount for CAN filter removal","id":"CVE-2026-72113"},"products":["Linux"],"published":"2026-08-15","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":"A missing length validation in the Linux kernel CAN BCM module allows attackers to cause a denial of service via malformed RTR replies.","url":"https://insights.sbomify.com/CVE-2026-72114/"}
