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-2025-39853 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2025-39853/ (Markdown: https://insights.sbomify.com/CVE-2025-39853/index.md)","id":"CVE-2025-39853","markdown":"https://insights.sbomify.com/CVE-2025-39853/index.md","name":"CVE-2025-39853","record":{"aliases":["AZL-67523","AZL-74847","BELL-CVE-2025-39853","DEBIAN-CVE-2025-39853","GHSA-7fp7-xjmp-444h","ROOT-OS-DEBIAN-11-CVE-2025-39853","ROOT-OS-DEBIAN-12-CVE-2025-39853","ROOT-OS-DEBIAN-13-CVE-2025-39853","ROOT-OS-UBUNTU-2204-CVE-2025-39853","ROOT-OS-UBUNTU-2404-CVE-2025-39853","UBUNTU-CVE-2025-39853"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A flaw in the i40e network driver allows invalid memory access when the MAC list is empty, potentially causing a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ni40e: Fix potential invalid access when MAC list is empty\n\nlist_first_entry() never returns NULL - if the list is empty, it still\nreturns a pointer to an invalid object, leading to potential invalid\nmemory access when dereferenced.\n\nFix this by using list_first_entry_or_null instead of list_first_entry.","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":"i40e: Fix potential invalid access when MAC list is empty","id":"CVE-2025-39853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel"],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":8,"next":{"headline":"ice: fix NULL access of tx-\u003ein_use in ice_ll_ts_intr","id":"CVE-2025-39854"},"packages":[],"prev":{"headline":"net/tcp: Fix socket memory leak in TCP-AO failure handling for IPv6","id":"CVE-2025-39852"},"products":["Linux"],"published":"2025-09-19","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-12","vendors":["Linux"]},"summary":"A flaw in the i40e network driver allows invalid memory access when the MAC list is empty, potentially causing a system crash.","url":"https://insights.sbomify.com/CVE-2025-39853/"}
