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-2026-90132 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-2026-90132/ (Markdown: https://insights.sbomify.com/CVE-2026-90132/index.md)","id":"CVE-2026-90132","markdown":"https://insights.sbomify.com/CVE-2026-90132/index.md","name":"CVE-2026-90132","record":{"aliases":["DEBIAN-CVE-2026-90132","GHSA-fwfw-gmx6-hm94","UBUNTU-CVE-2026-90132"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Attackers can escalate privileges by writing to reserved NTFS extended attributes without CAP_SYS_ADMIN, requiring kernel patching.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: reject unprivileged writes to reserved $LX* xattrs\n\nReject setxattr of the reserved $LXUID, $LXGID, $LXMOD and $LXDEV names\nfrom userspace unless the caller has CAP_SYS_ADMIN.","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":"ntfs: reject unprivileged writes to reserved $LX* xattrs","id":"CVE-2026-90132","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"ntfs: Fix index_root heap OOB write in ntfs_ir_to_ib()","id":"CVE-2026-90133"},"packages":[],"prev":{"headline":"ntfs: serialize resident iomap reads with mrec_lock","id":"CVE-2026-90131"},"products":["Linux"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"Attackers can escalate privileges by writing to reserved NTFS extended attributes without CAP_SYS_ADMIN, requiring kernel patching.","url":"https://insights.sbomify.com/CVE-2026-90132/"}
