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-2026-40706 in the wild and no public exploit code.\n\nAffected product: Tuxera NTFS-3G. 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-2026-40706/ (Markdown: https://insights.sbomify.com/CVE-2026-40706/index.md)","id":"CVE-2026-40706","markdown":"https://insights.sbomify.com/CVE-2026-40706/index.md","name":"CVE-2026-40706","record":{"aliases":["ALPINE-CVE-2026-40706","AZL-83181","DEBIAN-CVE-2026-40706","GHSA-4cwv-5285-63v9","MGASA-2026-0118","OESA-2026-2100","OESA-2026-2101","OESA-2026-2102","OESA-2026-2103","OESA-2026-2104","SUSE-SU-2026:1571-1","SUSE-SU-2026:21432-1","UBUNTU-CVE-2026-40706","USN-8192-2","openSUSE-SU-2026:10614-1","openSUSE-SU-2026:20651-1"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NTFS filesystem driver","requires_auth":"none","summary":"Heap buffer overflow in NTFS-3G allows attackers to execute arbitrary code with root privileges via a malicious NTFS image.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"In NTFS-3G 2022.10.3 before 2026.2.25, a heap buffer overflow exists in ntfs_build_permissions_posix() in acls.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image.
