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-2025-68251 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-2025-68251/ (Markdown: https://insights.sbomify.com/CVE-2025-68251/index.md)","id":"CVE-2025-68251","markdown":"https://insights.sbomify.com/CVE-2025-68251/index.md","name":"CVE-2025-68251","record":{"aliases":["AZL-87137","BELL-CVE-2025-68251","DEBIAN-CVE-2025-68251","GHSA-8mgh-pc39-hmfh","ROOT-OS-DEBIAN-13-CVE-2025-68251","ROOT-OS-UBUNTU-2404-CVE-2025-68251","UBUNTU-CVE-2025-68251"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A crafted EROFS image can cause an infinite loop in the Linux kernel, leading to a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nerofs: avoid infinite loops due to corrupted subpage compact indexes\n\nRobert reported an infinite loop observed by two crafted images.\n\nThe root cause is that `clusterofs` can be larger than `lclustersize`\nfor !NONHEAD `lclusters` in corrupted subpage compact indexes, e.g.:\n\n  blocksize = lclustersize = 512   lcn = 6   clusterofs = 515\n\nMove the corresponding check for full compress indexes to\n`z_erofs_load_lcluster_from_disk()` to also cover subpage compact\ncompress indexes.\n\nIt also fixes the position of `m-\u003etype \u003e= Z_EROFS_LCLUSTER_TYPE_MAX`\ncheck, since it should be placed right after\n`z_erofs_load_{compact,full}_lcluster()`.","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":"erofs: avoid infinite loops due to corrupted subpage compact indexes","id":"CVE-2025-68251","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"misc: fastrpc: Fix dma_buf object leak in fastrpc_map_lookup","id":"CVE-2025-68252"},"packages":[],"prev":{"headline":"hung_task: fix warnings caused by unaligned lock pointers","id":"CVE-2025-68250"},"products":["Linux"],"published":"2025-12-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"A crafted EROFS image can cause an infinite loop in the Linux kernel, leading to a denial of service.","url":"https://insights.sbomify.com/CVE-2025-68251/"}
