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-2026-45901 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-45901/ (Markdown: https://insights.sbomify.com/CVE-2026-45901/index.md)","id":"CVE-2026-45901","markdown":"https://insights.sbomify.com/CVE-2026-45901/index.md","name":"CVE-2026-45901","record":{"aliases":["AZL-88692","BELL-CVE-2026-45901","DEBIAN-CVE-2026-45901","GHSA-jhvq-4r2h-7c2q","ROOT-OS-DEBIAN-12-CVE-2026-45901","ROOT-OS-DEBIAN-13-CVE-2026-45901","ROOT-OS-UBUNTU-2404-CVE-2026-45901","UBUNTU-CVE-2026-45901"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel netfilter","requires_auth":"low_privilege","summary":"A circular lock dependency in the Linux kernel netfilter subsystem can cause a deadlock during concurrent reset and list operations, leading to denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: revert commit_mutex usage in reset path\n\nIt causes circular lock dependency between commit_mutex, nfnl_subsys_ipset\nand nlk_cb_mutex when nft reset, ipset list, and iptables-nft with '-m set'\nrule run at the same time.\n\nPrevious patches made it safe to run individual reset handlers concurrently\nso commit_mutex is no longer required to prevent this.","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: nf_tables: revert commit_mutex usage in reset path","id":"CVE-2026-45901","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"power: supply: bq256xx: Fix use-after-free in power_supply_changed()","id":"CVE-2026-45902"},"packages":[],"prev":{"headline":"crypto: caam - fix netdev memory leak in dpaa2_caam_probe","id":"CVE-2026-45900"},"products":["Linux"],"published":"2026-05-27","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"A circular lock dependency in the Linux kernel netfilter subsystem can cause a deadlock during concurrent reset and list operations, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-45901/"}
