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-2023-53549 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-2023-53549/ (Markdown: https://insights.sbomify.com/CVE-2023-53549/index.md)","id":"CVE-2023-53549","markdown":"https://insights.sbomify.com/CVE-2023-53549/index.md","name":"CVE-2023-53549","record":{"aliases":["BELL-CVE-2023-53549","DEBIAN-CVE-2023-53549","GHSA-ff5r-w44x-rq6x","UBUNTU-CVE-2023-53549"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An attacker can cause a denial of service via soft lockups by adding or deleting large numbers of elements in ipset.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: ipset: Rework long task execution when adding/deleting entries\n\nWhen adding/deleting large number of elements in one step in ipset, it can\ntake a reasonable amount of time and can result in soft lockup errors. The\npatch 5f7b51bf09ba (\"netfilter: ipset: Limit the maximal range of\nconsecutive elements to add/delete\") tried to fix it by limiting the max\nelements to process at all. However it was not enough, it is still possible\nthat we get hung tasks. Lowering the limit is not reasonable, so the\napproach in this patch is as follows: rely on the method used at resizing\nsets and save the state when we reach a smaller internal batch limit,\nunlock/lock and proceed from the saved state. Thus we can avoid long\ncontinuous tasks and at the same time removed the limit to add/delete large\nnumber of elements in one step.\n\nThe nfnl mutex is held during the whole operation which prevents one to\nissue other ipset commands in parallel.","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: ipset: Rework long task execution when adding/deleting entries","id":"CVE-2023-53549","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"cpufreq: amd-pstate: fix global sysfs attribute type","id":"CVE-2023-53550"},"packages":[],"prev":{"headline":"net: usbnet: Fix WARNING in usbnet_start_xmit/usb_submit_urb","id":"CVE-2023-53548"},"products":["Linux"],"published":"2025-10-04","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":"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":"2026-05-23","vendors":["Linux"]},"summary":"An attacker can cause a denial of service via soft lockups by adding or deleting large numbers of elements in ipset.","url":"https://insights.sbomify.com/CVE-2023-53549/"}
