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-2025-38639 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-2025-38639/ (Markdown: https://insights.sbomify.com/CVE-2025-38639/index.md)","id":"CVE-2025-38639","markdown":"https://insights.sbomify.com/CVE-2025-38639/index.md","name":"CVE-2025-38639","record":{"aliases":["AZL-66617","AZL-73488","BELL-CVE-2025-38639","DEBIAN-CVE-2025-38639","GHSA-44mx-f9p7-87j2","ROOT-OS-DEBIAN-11-CVE-2025-38639","ROOT-OS-DEBIAN-12-CVE-2025-38639","ROOT-OS-DEBIAN-13-CVE-2025-38639","ROOT-OS-UBUNTU-2204-CVE-2025-38639","ROOT-OS-UBUNTU-2404-CVE-2025-38639","UBUNTU-CVE-2025-38639"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A missing null-termination check in the Linux kernel netfilter module allows out-of-bounds reads, potentially disclosing sensitive memory contents.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: xt_nfacct: don't assume acct name is null-terminated\n\nBUG: KASAN: slab-out-of-bounds in .. lib/vsprintf.c:721\nRead of size 1 at addr ffff88801eac95c8 by task syz-executor183/5851\n[..]\n string+0x231/0x2b0 lib/vsprintf.c:721\n vsnprintf+0x739/0xf00 lib/vsprintf.c:2874\n [..]\n nfacct_mt_checkentry+0xd2/0xe0 net/netfilter/xt_nfacct.c:41\n xt_check_match+0x3d1/0xab0 net/netfilter/x_tables.c:523\n\nnfnl_acct_find_get() handles non-null input, but the error\nprintk relied on its presence.","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":"netfilter: xt_nfacct: don't assume acct name is null-terminated","id":"CVE-2025-38639","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel"],"type":"information_disclosure","year":"2025"},"n_packages":0,"n_references":9,"next":{"headline":"bpf: Disable migration in nf_hook_run_bpf().","id":"CVE-2025-38640"},"packages":[],"prev":{"headline":"ipv6: add a retry logic in net6_rt_notify()","id":"CVE-2025-38638"},"products":["Linux"],"published":"2025-08-22","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A missing null-termination check in the Linux kernel netfilter module allows out-of-bounds reads, potentially disclosing sensitive memory contents.","url":"https://insights.sbomify.com/CVE-2025-38639/"}
