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-2024-35844 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-2024-35844/ (Markdown: https://insights.sbomify.com/CVE-2024-35844/index.md)","id":"CVE-2024-35844","markdown":"https://insights.sbomify.com/CVE-2024-35844/index.md","name":"CVE-2024-35844","record":{"aliases":["BELL-CVE-2024-35844","DEBIAN-CVE-2024-35844","GHSA-7f94-q32g-r8m7","ROOT-OS-DEBIAN-11-CVE-2024-35844","UBUNTU-CVE-2024-35844"],"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 logic error in the Linux kernel's f2fs compression module causes files to become unrepairable when disk space is exhausted, leading to data loss or denial of service.","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":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: compress: fix reserve_cblocks counting error when out of space\n\nWhen a file only needs one direct_node, performing the following\noperations will cause the file to be unrepairable:\n\nunisoc # ./f2fs_io compress test.apk\nunisoc #df -h | grep dm-48\n/dev/block/dm-48 112G 112G 1.2M 100% /data\n\nunisoc # ./f2fs_io release_cblocks test.apk\n924\nunisoc # df -h | grep dm-48\n/dev/block/dm-48 112G 112G 4.8M 100% /data\n\nunisoc # dd if=/dev/random of=file4 bs=1M count=3\n3145728 bytes (3.0 M) copied, 0.025 s, 120 M/s\nunisoc # df -h | grep dm-48\n/dev/block/dm-48 112G 112G 1.8M 100% /data\n\nunisoc # ./f2fs_io reserve_cblocks test.apk\nF2FS_IOC_RESERVE_COMPRESS_BLOCKS failed: No space left on device\n\nadb reboot\nunisoc # df -h  | grep dm-48\n/dev/block/dm-48             112G 112G   11M 100% /data\nunisoc # ./f2fs_io reserve_cblocks test.apk\n0\n\nThis is because the file has only one direct_node.
