It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2019-19447 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-2019-19447/ (Markdown: https://insights.sbomify.com/CVE-2019-19447/index.md)","id":"CVE-2019-19447","markdown":"https://insights.sbomify.com/CVE-2019-19447/index.md","name":"CVE-2019-19447","record":{"aliases":["DEBIAN-CVE-2019-19447","GHSA-jx5x-5x47-rh28","UBUNTU-CVE-2019-19447"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A local attacker can trigger a use-after-free in the Linux kernel ext4 filesystem by mounting a crafted image, potentially leading to code execution or privilege escalation.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"linux_kernel","vendor":"linux"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"cloud_backup","vendor":"netapp"},{"product":"data_availability_services","vendor":"netapp"},{"product":"hci_baseboard_management_controller","vendor":"netapp"},{"product":"solidfire_baseboard_management_controller","vendor":"netapp"},{"product":"steelstore_cloud_integrated_storage","vendor":"netapp"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-11-27","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-11-27T10:49:52Z","kind":"github_poc","ref":"https://github.com/Trinadh465/linux-4.19.72_CVE-2019-19447","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Use after free in n/a","id":"CVE-2019-19447","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel","netapp:active_iq_unified_manager","netapp:cloud_backup","netapp:data_availability_services","netapp:steelstore_cloud_integrated_storage"],"type":"use_after_free","year":"2019"},"n_packages":0,"n_references":6,"next":{"headline":"Use after free in n/a","id":"CVE-2019-19448"},"packages":[],"prev":{"headline":"Information disclosure in HUAWEI P30","id":"CVE-2019-19441"},"products":["n/a"],"published":"2019-12-08","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"A local attacker can trigger a use-after-free in the Linux kernel ext4 filesystem by mounting a crafted image, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2019-19447/"}
