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-2024-53220 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-2024-53220/ (Markdown: https://insights.sbomify.com/CVE-2024-53220/index.md)","id":"CVE-2024-53220","markdown":"https://insights.sbomify.com/CVE-2024-53220/index.md","name":"CVE-2024-53220","record":{"aliases":["BELL-CVE-2024-53220","DEBIAN-CVE-2024-53220","GHSA-44hx-9778-xh92","ROOT-OS-DEBIAN-11-CVE-2024-53220","ROOT-OS-UBUNTU-2204-CVE-2024-53220","UBUNTU-CVE-2024-53220"],"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 local attacker can trigger a kernel panic in the f2fs filesystem by exploiting incorrect dirty data accounting when checkpoint disabling and LFS mode are enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: fix to account dirty data in __get_secs_required()\n\nIt will trigger system panic w/ testcase in [1]:\n\n------------[ cut here ]------------\nkernel BUG at fs/f2fs/segment.c:2752!\nRIP: 0010:new_curseg+0xc81/0x2110\nCall Trace:\n f2fs_allocate_data_block+0x1c91/0x4540\n do_write_page+0x163/0xdf0\n f2fs_outplace_write_data+0x1aa/0x340\n f2fs_do_write_data_page+0x797/0x2280\n f2fs_write_single_data_page+0x16cd/0x2190\n f2fs_write_cache_pages+0x994/0x1c80\n f2fs_write_data_pages+0x9cc/0xea0\n do_writepages+0x194/0x7a0\n filemap_fdatawrite_wbc+0x12b/0x1a0\n __filemap_fdatawrite_range+0xbb/0xf0\n file_write_and_wait_range+0xa1/0x110\n f2fs_do_sync_file+0x26f/0x1c50\n f2fs_sync_file+0x12b/0x1d0\n vfs_fsync_range+0xfa/0x230\n do_fsync+0x3d/0x80\n __x64_sys_fsync+0x37/0x50\n x64_sys_call+0x1e88/0x20d0\n do_syscall_64+0x4b/0x110\n entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\nThe root cause is if checkpoint_disabling and lfs_mode are both on,\nit will trigger OPU for all overwritten data, it may cost more free\nsegment than expected, so f2fs must account those data correctly to\ncalculate cosumed free segments later, and return ENOSPC earlier to\navoid run out of free segment during block allocation.\n\n[1] https://lore.kernel.org/fstests/20241015025106.3203676-1-chao@kernel.org/","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 account dirty data in __get_secs_required()","id":"CVE-2024-53220","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":5,"next":{"headline":"f2fs: fix null-ptr-deref in f2fs_submit_page_bio()","id":"CVE-2024-53221"},"packages":[],"prev":{"headline":"virtiofs: use pages instead of pointer for kernel direct IO","id":"CVE-2024-53219"},"products":["Linux"],"published":"2024-12-27","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A local attacker can trigger a kernel panic in the f2fs filesystem by exploiting incorrect dirty data accounting when checkpoint disabling and LFS mode are enabled.","url":"https://insights.sbomify.com/CVE-2024-53220/"}
