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-2026-98681 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-2026-98681/ (Markdown: https://insights.sbomify.com/CVE-2026-98681/index.md)","id":"CVE-2026-98681","markdown":"https://insights.sbomify.com/CVE-2026-98681/index.md","name":"CVE-2026-98681","record":{"aliases":["AZL-109164","BELL-CVE-2026-98681","DEBIAN-CVE-2026-98681","GHSA-f6j4-gqwr-mpr2","UBUNTU-CVE-2026-98681"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"Concurrent updates to SMB client flags can corrupt state due to race conditions, potentially causing data corruption or crashes.","user_interaction":"not_required","vuln_class":"race_condition"},"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\nsmb: client: split cifsFileInfo bitfields to avoid shared-byte RMW races\n\nThe invalidHandle, swapfile, oplock_break_cancelled, offload,\nand status_file_deleted fields are stored in the same bitfield byte\nin struct cifsFileInfo, but are updated in different code paths that\nmay run simultaneously, and are protected by different locks.
