It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-45935 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-2026-45935/ (Markdown: https://insights.sbomify.com/CVE-2026-45935/index.md)","id":"CVE-2026-45935","markdown":"https://insights.sbomify.com/CVE-2026-45935/index.md","name":"CVE-2026-45935","record":{"aliases":["BELL-CVE-2026-45935","DEBIAN-CVE-2026-45935","GHSA-4cvx-h6xx-mj53","ROOT-OS-UBUNTU-2204-CVE-2026-45935","ROOT-OS-UBUNTU-2404-CVE-2026-45935","UBUNTU-CVE-2026-45935"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel NTFS3","requires_auth":"none","summary":"A slab-out-of-bounds read in the Linux kernel NTFS3 driver allows attackers to trigger heap buffer overflows via maliciously crafted NTFS images, potentially leading to code execution or system crashes.","user_interaction":"required","vuln_class":"memory_corruption"},"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:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: Fix slab-out-of-bounds read in DeleteIndexEntryRoot\n\nIn the 'DeleteIndexEntryRoot' case of the 'do_action' function, the\nentry size ('esize') is retrieved from the log record without adequate\nbounds checking.\n\nSpecifically, the code calculates the end of the entry ('e2') using:\n    e2 = Add2Ptr(e1, esize);\n\nIt then calculates the size for memmove using 'PtrOffset(e2, ...)',\nwhich subtracts the end pointer from the buffer limit.
