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-2026-68316 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-2026-68316/ (Markdown: https://insights.sbomify.com/CVE-2026-68316/index.md)","id":"CVE-2026-68316","markdown":"https://insights.sbomify.com/CVE-2026-68316/index.md","name":"CVE-2026-68316","record":{"aliases":["DEBIAN-CVE-2026-68316","GHSA-35p7-3vg5-ccvp","UBUNTU-CVE-2026-68316"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"Incorrect element size calculation in the Ethos-U accelerator driver can lead to buffer overflows, potentially allowing attackers to cause denial of service or execute arbitrary code.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel: ethosu: Fix element size accounting for cmd stream validation\n\nThere are 2 issues with the element size handling in the command stream\nvalidation which result in too small of a size calculated when the\nelement size is 16/32/64 bits.\n\nFor NHWC format, the element size is simply missing from the\ncalculation.\n\nThe bitfield for the element size is different between IFM/IFM2 and\nOFM.
