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-2026-90419 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-2026-90419/ (Markdown: https://insights.sbomify.com/CVE-2026-90419/index.md)","id":"CVE-2026-90419","markdown":"https://insights.sbomify.com/CVE-2026-90419/index.md","name":"CVE-2026-90419","record":{"aliases":["AZL-102722","BELL-CVE-2026-90419","DEBIAN-CVE-2026-90419","GHSA-mf3g-x95g-wcp3","UBUNTU-CVE-2026-90419"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel filesystem","requires_auth":"none","summary":"A malformed nilfs2 filesystem image can cause an out-of-bounds read in the Linux kernel, potentially leading to information disclosure or system crashes.","user_interaction":"required","vuln_class":"memory_corruption"},"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:N/UI:R/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: prevent out-of-bounds read in super root block parsing\n\nsuper-root inode metadata size is trusted before nilfs_read_inode_common().\n\nReject super-root inode sizes whose computed on-disk footprint exceeds the\nfilesystem block size.
