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-2024-49966 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2024-49966/ (Markdown: https://insights.sbomify.com/CVE-2024-49966/index.md)","id":"CVE-2024-49966","markdown":"https://insights.sbomify.com/CVE-2024-49966/index.md","name":"CVE-2024-49966","record":{"aliases":["BELL-CVE-2024-49966","DEBIAN-CVE-2024-49966","GHSA-w8mx-fc3q-r9qv","UBUNTU-CVE-2024-49966"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel OCFS2 filesystem can cause a system crash when error handling frees active work items.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: cancel dqi_sync_work before freeing oinfo\n\nocfs2_global_read_info() will initialize and schedule dqi_sync_work at the\nend, if error occurs after successfully reading global quota, it will\ntrigger the following warning with CONFIG_DEBUG_OBJECTS_* enabled:\n\nODEBUG: free active (active state 0) object: 00000000d8b0ce28 object type: timer_list hint: qsync_work_fn+0x0/0x16c\n\nThis reports that there is an active delayed work when freeing oinfo in\nerror handling, so cancel dqi_sync_work first.
