It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-20793 and fix it if it is affected.\n\nWhat it is: CVE-2026-20793 is a medium-severity denial of service vulnerability in Intel(R) QAT software drivers for Windows, published on 12 May 2026. 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-2026-20793 in the wild and no public exploit code.\n\nAffected product: Intel(R) QAT software drivers for Windows. 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-2026-20793/ (Markdown: https://insights.sbomify.com/CVE-2026-20793/index.md)","id":"CVE-2026-20793","markdown":"https://insights.sbomify.com/CVE-2026-20793/index.md","name":"CVE-2026-20793","record":{"aliases":["GHSA-w95w-74rp-vcx9"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel QAT Windows driver","requires_auth":"low_privilege","summary":"An unprivileged local attacker can cause a denial of service in Intel QAT Windows drivers by exploiting unchecked return values.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[{"product":"quickassist_technology","vendor":"intel"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-252","name":"Unchecked Return Value"}],"description":"Unchecked return value for some Intel(R) QAT software drivers for Windows before version 1.13 within Ring 3: User Applications may allow a denial of service.
