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-2026-71226 in the wild and no public exploit code.\n\nAffected product: Redhat Enterprise 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-2026-71226/ (Markdown: https://insights.sbomify.com/CVE-2026-71226/index.md)","id":"CVE-2026-71226","markdown":"https://insights.sbomify.com/CVE-2026-71226/index.md","name":"CVE-2026-71226","record":{"aliases":["ALPINE-CVE-2026-71226","AZL-94658","BELL-CVE-2026-71226","DEBIAN-CVE-2026-71226","GHSA-rg4h-x337-qh8m","UBUNTU-CVE-2026-71226"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux crypto library","requires_auth":"none","summary":"Attackers can trigger memory corruption in libkcapi's AIO path, potentially leading to code execution or privilege escalation on affected Linux systems.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"enterprise_linux","vendor":"redhat"},{"product":"hardened_images","vendor":"redhat"},{"product":"openshift_container_platform","vendor":"redhat"},{"product":"libkcapi","vendor":"smuellerdd"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers.","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":"Libkcapi: memory corruption via uncanceled aio requests on error in libkcapi's one-shot aio path","id":"CVE-2026-71226","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"redhat:enterprise_linux","products":["redhat:enterprise_linux","redhat:hardened_images","redhat:openshift_container_platform"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"Denial of service in Red Hat Enterprise Linux 10","id":"CVE-2026-71227"},"packages":[],"prev":{"headline":"Libkcapi: iv reuse in libkcapi one-shot symmetric cipher chunking causes cipher state reset across chunk boundaries","id":"CVE-2026-71225"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 10.0 Extended Update Support","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9","Red Hat Enterprise Linux 9.6 Extended Update Support","Red Hat Hardened Images","Red Hat OpenShift Container Platform 4","libkcapi"],"published":"2026-08-05","related":[{"cvss_score":9.8,"headline":"Red Hat JBoss RichFaces Framework Expression Language Injection","id":"CVE-2018-14667","kev_date_added":"2023-09-28","published":"2018-11-06"},{"cvss_score":9.8,"headline":"Missing fixes for CVE-2021-40438 and CVE-2021-26691 in the versions of httpd, as shipped in Red Hat Enterprise Linux 8.5.0, causes a securit","id":"CVE-2021-20325","kev_date_added":null,"published":"2022-02-18"},{"cvss_score":9.8,"headline":"Memory corruption in libwebp","id":"CVE-2018-25011","kev_date_added":null,"published":"2021-05-21"},{"cvss_score":9.8,"headline":"Other in libwebp","id":"CVE-2018-25014","kev_date_added":null,"published":"2021-05-21"},{"cvss_score":9.8,"headline":"Supply chain in redhat-upgrade-tool","id":"CVE-2014-3585","kev_date_added":null,"published":"2019-11-22"},{"cvss_score":9.3,"headline":"Squid: request/response smuggling in http/1.1 and icap","id":"CVE-2023-46846","kev_date_added":null,"published":"2023-11-03"},{"cvss_score":9.1,"headline":"Memory corruption in libwebp","id":"CVE-2018-25009","kev_date_added":null,"published":"2021-05-21"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-22","vendors":["Red Hat","Stephan Muelle"]},"summary":"Attackers can trigger memory corruption in libkcapi's AIO path, potentially leading to code execution or privilege escalation on affected Linux systems.","url":"https://insights.sbomify.com/CVE-2026-71226/"}
