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-2025-40077 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-2025-40077/ (Markdown: https://insights.sbomify.com/CVE-2025-40077/index.md)","id":"CVE-2025-40077","markdown":"https://insights.sbomify.com/CVE-2025-40077/index.md","name":"CVE-2025-40077","record":{"aliases":["BELL-CVE-2025-40077","DEBIAN-CVE-2025-40077","GHSA-4hvf-57gh-hgxp","ROOT-OS-DEBIAN-11-CVE-2025-40077","ROOT-OS-DEBIAN-12-CVE-2025-40077","ROOT-OS-DEBIAN-13-CVE-2025-40077","ROOT-OS-UBUNTU-2204-CVE-2025-40077","ROOT-OS-UBUNTU-2404-CVE-2025-40077","UBUNTU-CVE-2025-40077"],"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":"An integer overflow in the Linux kernel f2fs filesystem can lead to denial of service, requiring local access to exploit.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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\nf2fs: fix to avoid overflow while left shift operation\n\nShould cast type of folio-\u003eindex from pgoff_t to loff_t to avoid overflow\nwhile left shift operation.","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 avoid overflow while left shift operation","id":"CVE-2025-40077","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"bpf: Explicitly check accesses to bpf_sock_addr","id":"CVE-2025-40078"},"packages":[],"prev":{"headline":"PCI: rcar-host: Pass proper IRQ domain to generic_handle_domain_irq()","id":"CVE-2025-40076"},"products":["Linux"],"published":"2025-10-28","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":"2026-05-11","vendors":["Linux"]},"summary":"An integer overflow in the Linux kernel f2fs filesystem can lead to denial of service, requiring local access to exploit.","url":"https://insights.sbomify.com/CVE-2025-40077/"}
