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-2023-54124 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-2023-54124/ (Markdown: https://insights.sbomify.com/CVE-2023-54124/index.md)","id":"CVE-2023-54124","markdown":"https://insights.sbomify.com/CVE-2023-54124/index.md","name":"CVE-2023-54124","record":{"aliases":["BELL-CVE-2023-54124","DEBIAN-CVE-2023-54124","GHSA-f6pj-88hq-4vr4","UBUNTU-CVE-2023-54124"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel f2fs","requires_auth":"low_privilege","summary":"A bug in the Linux kernel's f2fs filesystem causes a kernel panic during unmount when a checkpoint error is set, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: fix to drop all dirty pages during umount() if cp_error is set\n\nxfstest generic/361 reports a bug as below:\n\nf2fs_bug_on(sbi, sbi-\u003efsync_node_num);\n\nkernel BUG at fs/f2fs/super.c:1627!\nRIP: 0010:f2fs_put_super+0x3a8/0x3b0\nCall Trace:\n generic_shutdown_super+0x8c/0x1b0\n kill_block_super+0x2b/0x60\n kill_f2fs_super+0x87/0x110\n deactivate_locked_super+0x39/0x80\n deactivate_super+0x46/0x50\n cleanup_mnt+0x109/0x170\n __cleanup_mnt+0x16/0x20\n task_work_run+0x65/0xa0\n exit_to_user_mode_prepare+0x175/0x190\n syscall_exit_to_user_mode+0x25/0x50\n do_syscall_64+0x4c/0x90\n entry_SYSCALL_64_after_hwframe+0x72/0xdc\n\nDuring umount(), if cp_error is set, f2fs_wait_on_all_pages() should\nnot stop waiting all F2FS_WB_CP_DATA pages to be writebacked, otherwise,\nfsync_node_num can be non-zero after f2fs_wait_on_all_pages() causing\nthis bug.\n\nIn this case, to avoid deadloop in f2fs_wait_on_all_pages(), it needs\nto drop all dirty pages rather than redirtying them.","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":"f2fs: fix to drop all dirty pages during umount() if cp_error is set","id":"CVE-2023-54124","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":7,"next":{"headline":"fs/ntfs3: Return error for inconsistent extended attributes","id":"CVE-2023-54125"},"packages":[],"prev":{"headline":"md/raid10: fix memleak for 'conf-\u003ebio_split'","id":"CVE-2023-54123"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A bug in the Linux kernel's f2fs filesystem causes a kernel panic during unmount when a checkpoint error is set, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2023-54124/"}
