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-2022-21819 and fix it if it is affected.\n\nWhat it is: CVE-2022-21819 is a high-severity vulnerability in NVIDIA Jetson Nano, Jetson Nano 2GB, published on 11 Mar 2022. 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-2022-21819 in the wild and no public exploit code.\n\nAffected product: NVIDIA Jetson Nano, Jetson Nano 2GB. 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-2022-21819/ (Markdown: https://insights.sbomify.com/CVE-2022-21819/index.md)","id":"CVE-2022-21819","markdown":"https://insights.sbomify.com/CVE-2022-21819/index.md","name":"CVE-2022-21819","record":{"aliases":["GHSA-5q8q-7qqw-cmj3"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation","data_read","data_modify","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NVIDIA Jetson Linux","requires_auth":"none","summary":"An IOMMU misconfiguration in NVIDIA Jetson Linux allows physical attackers to access system memory via PCI, enabling code execution and privilege escalation.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"nvidia","cpe":[{"product":"jetson_linux","vendor":"nvidia"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"NVIDIA distributions of Jetson Linux contain a vulnerability where an error in the IOMMU configuration may allow an unprivileged attacker with physical access to the board direct read/write access to the entire system address space through the PCI bus.
