An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72210 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-2026-72210/ (Markdown: https://insights.sbomify.com/CVE-2026-72210/index.md)","id":"CVE-2026-72210","markdown":"https://insights.sbomify.com/CVE-2026-72210/index.md","name":"CVE-2026-72210","record":{"aliases":["DEBIAN-CVE-2026-72210","GHSA-hpv2-jq93-768m","UBUNTU-CVE-2026-72210"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel NTFS","requires_auth":"none","summary":"An off-by-one error in the Linux kernel NTFS driver allows out-of-bounds reads, potentially leading to information disclosure or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: fix off-by-one in mapping pairs decoding bounds checks\n\nIn ntfs_mapping_pairs_decompress(), attr_end points one byte past the\nend of the attribute record:\n\n    attr_end = (u8 *)attr + le32_to_cpu(attr-\u003elength);\n\nThe two bounds checks validating that mapping pair data bytes fit within\nthe attribute use strict greater-than (\u003e), which allows a one-byte\nout-of-bounds read when the data extends exactly to attr_end:\n\n  b = *buf \u0026 0xf;\n  if (b) {\n      if (unlikely(buf + b \u003e attr_end))   // off-by-one\n          goto io_error;\n      for (deltaxcn = (s8)buf[b--]; b; b--)\n          deltaxcn = (deltaxcn \u003c\u003c 8) + buf[b];\n  }\n\nWhen buf + b == attr_end, the check evaluates to false and buf[b] reads\none byte past the valid attribute boundary.
