An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-53705 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-2023-53705/ (Markdown: https://insights.sbomify.com/CVE-2023-53705/index.md)","id":"CVE-2023-53705","markdown":"https://insights.sbomify.com/CVE-2023-53705/index.md","name":"CVE-2023-53705","record":{"aliases":["BELL-CVE-2023-53705","DEBIAN-CVE-2023-53705","GHSA-27mw-8p8v-6j5h","UBUNTU-CVE-2023-53705"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An out-of-bounds access in the Linux kernel IPv6 implementation allows attackers to cause denial of service or potentially execute code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nipv6: Fix out-of-bounds access in ipv6_find_tlv()\n\noptlen is fetched without checking whether there is more than one byte to parse.\nIt can lead to out-of-bounds access.\n\nFound by InfoTeCS on behalf of Linux Verification Center\n(linuxtesting.org) with SVACE.","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":"ipv6: Fix out-of-bounds access in ipv6_find_tlv()","id":"CVE-2023-53705","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":8,"next":{"headline":"mm/vmemmap/devdax: fix kernel crash when probing devdax devices","id":"CVE-2023-53706"},"packages":[],"prev":{"headline":"clk: imx: clk-imx8mp: improve error handling in imx8mp_clocks_probe()","id":"CVE-2023-53704"},"products":["Linux"],"published":"2025-10-22","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"An out-of-bounds access in the Linux kernel IPv6 implementation allows attackers to cause denial of service or potentially execute code.","url":"https://insights.sbomify.com/CVE-2023-53705/"}
