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-2026-31693 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-31693/ (Markdown: https://insights.sbomify.com/CVE-2026-31693/index.md)","id":"CVE-2026-31693","markdown":"https://insights.sbomify.com/CVE-2026-31693/index.md","name":"CVE-2026-31693","record":{"aliases":["BELL-CVE-2026-31693","DEBIAN-CVE-2026-31693","GHSA-v5v4-gvc3-q8x8","ROOT-OS-UBUNTU-2204-CVE-2026-31693","ROOT-OS-UBUNTU-2404-CVE-2026-31693","UBUNTU-CVE-2026-31693"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel CIFS","requires_auth":"low_privilege","summary":"Missing variable initializations in the Linux kernel CIFS module during request replays could lead to undefined behavior or logic errors.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"},{"id":"CWE-665","name":"Improper Initialization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncifs: some missing initializations on replay\n\nIn several places in the code, we have a label to signify\nthe start of the code where a request can be replayed if\nnecessary.
