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-2019-19318 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2019-19318/ (Markdown: https://insights.sbomify.com/CVE-2019-19318/index.md)","id":"CVE-2019-19318","markdown":"https://insights.sbomify.com/CVE-2019-19318/index.md","name":"CVE-2019-19318","record":{"aliases":["DEBIAN-CVE-2019-19318","GHSA-r6gp-mqm3-8pv6","UBUNTU-CVE-2019-19318"],"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":"high_privilege","summary":"A use-after-free in the Linux kernel allows attackers to execute arbitrary code or escalate privileges by mounting a crafted btrfs image twice.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"aff_a400_firmware","vendor":"netapp"},{"product":"aff_a700s_firmware","vendor":"netapp"},{"product":"data_availability_services","vendor":"netapp"},{"product":"fas8300_firmware","vendor":"netapp"},{"product":"fas8700_firmware","vendor":"netapp"},{"product":"h610s_firmware","vendor":"netapp"},{"product":"hci_management_node","vendor":"netapp"},{"product":"solidfire","vendor":"netapp"},{"product":"steelstore_cloud_integrated_storage","vendor":"netapp"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":4.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel 5.3.11, mounting a crafted btrfs image twice can cause an rwsem_down_write_slowpath use-after-free because (in rwsem_can_spin_on_owner in kernel/locking/rwsem.c) rwsem_owner_flags returns an already freed pointer,","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":"Use after free in n/a","id":"CVE-2019-19318","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux","linux:linux_kernel","netapp:active_iq_unified_manager","netapp:data_availability_services","netapp:h610s_firmware","netapp:hci_management_node","netapp:solidfire","netapp:steelstore_cloud_integrated_storage","opensuse:leap"],"type":"use_after_free","year":"2019"},"n_packages":0,"n_references":5,"next":{"headline":"Use after free in n/a","id":"CVE-2019-19319"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2019-19317"},"products":["n/a"],"published":"2019-11-27","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"A use-after-free in the Linux kernel allows attackers to execute arbitrary code or escalate privileges by mounting a crafted btrfs image twice.","url":"https://insights.sbomify.com/CVE-2019-19318/"}
