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-2025-40200 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-2025-40200/ (Markdown: https://insights.sbomify.com/CVE-2025-40200/index.md)","id":"CVE-2025-40200","markdown":"https://insights.sbomify.com/CVE-2025-40200/index.md","name":"CVE-2025-40200","record":{"aliases":["AZL-70073","BELL-CVE-2025-40200","DEBIAN-CVE-2025-40200","GHSA-w4gv-xmrm-6wxx","ROOT-OS-UBUNTU-2404-CVE-2025-40200","UBUNTU-CVE-2025-40200"],"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 local attacker can cause a kernel warning and potential denial of service by mounting a crafted Squashfs image with negative file sizes.","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\nSquashfs: reject negative file sizes in squashfs_read_inode()\n\nSyskaller reports a \"WARNING in ovl_copy_up_file\" in overlayfs.\n\nThis warning is ultimately caused because the underlying Squashfs file\nsystem returns a file with a negative file size.\n\nThis commit checks for a negative file size and returns EINVAL.\n\n[phillip@squashfs.org.uk: only need to check 64 bit quantity]","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":"Squashfs: reject negative file sizes in squashfs_read_inode()","id":"CVE-2025-40200","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2025"},"n_packages":0,"n_references":8,"next":{"headline":"kernel/sys.c: fix the racy usage of task_lock(tsk-\u003egroup_leader) in sys_prlimit64() paths","id":"CVE-2025-40201"},"packages":[],"prev":{"headline":"page_pool: Fix PP_MAGIC_MASK to avoid crashing on some 32-bit arches","id":"CVE-2025-40199"},"products":["Linux"],"published":"2025-11-12","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":"A local attacker can cause a kernel warning and potential denial of service by mounting a crafted Squashfs image with negative file sizes.","url":"https://insights.sbomify.com/CVE-2025-40200/"}
