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-2026-72041 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-2026-72041/ (Markdown: https://insights.sbomify.com/CVE-2026-72041/index.md)","id":"CVE-2026-72041","markdown":"https://insights.sbomify.com/CVE-2026-72041/index.md","name":"CVE-2026-72041","record":{"aliases":["BELL-CVE-2026-72041","DEBIAN-CVE-2026-72041","GHSA-55rh-f38r-fhcc","UBUNTU-CVE-2026-72041"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A bug in Linux kernel ESP-in-TCP handling caused incorrect memory accounting during partial sends, potentially leading to resource inconsistencies.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-664","name":"Improper Control of a Resource Through its Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nespintcp: use sk_msg_free_partial to fix partial send\n\nsk_msg_free_partial() ensures consistency of the skmsg at every\niteration, without having to manually handle uncharges and offsets.\nThis simplifies the code, and fixes some bugs in skmsg accounting when\nwe don't send the full contents.","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":"espintcp: use sk_msg_free_partial to fix partial send","id":"CVE-2026-72041","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"ipmi: Fix user refcount underflow in event delivery","id":"CVE-2026-72042"},"packages":[],"prev":{"headline":"ipmi: fix refcount leak in i_ipmi_request()","id":"CVE-2026-72040"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A bug in Linux kernel ESP-in-TCP handling caused incorrect memory accounting during partial sends, potentially leading to resource inconsistencies.","url":"https://insights.sbomify.com/CVE-2026-72041/"}
