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-2026-97551 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-2026-97551/ (Markdown: https://insights.sbomify.com/CVE-2026-97551/index.md)","id":"CVE-2026-97551","markdown":"https://insights.sbomify.com/CVE-2026-97551/index.md","name":"CVE-2026-97551","record":{"aliases":["BELL-CVE-2026-97551","DEBIAN-CVE-2026-97551","GHSA-hph3-hwfc-67wh","UBUNTU-CVE-2026-97551"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An integer overflow in XFS parent pointer updates causes filesystem shutdown, leading to denial of service for local attackers.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: initialise args-\u003etotal for parent pointer updates\n\nxfs_parent_da_args_init() builds an xfs_da_args from a zeroed\nxfs_parent_args (kmem_cache_zalloc), leaving args-\u003etotal == 0.\nxfs_da_grow_inode_int() treats that field as a running block reservation\nand subtracts from it; because it is an xfs_extlen_t (uint32_t), the\nfirst attr-fork growth wraps it to ~0U.
