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-2026-47503 in the wild and no public exploit code.\n\nAffected product: NVIDIA Virtual GPU Manager. 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-2026-47503/ (Markdown: https://insights.sbomify.com/CVE-2026-47503/index.md)","id":"CVE-2026-47503","markdown":"https://insights.sbomify.com/CVE-2026-47503/index.md","name":"CVE-2026-47503","record":{"aliases":["DEBIAN-CVE-2026-47503","GHSA-33rr-wch2-jq8g","UBUNTU-CVE-2026-47503"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation","data_modify","denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NVIDIA vGPU driver","requires_auth":"low_privilege","summary":"A guest VM user can trigger an out-of-bounds write in the NVIDIA vGPU plugin via crafted RPC messages, leading to code execution and privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"nvidia","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":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"NVIDIA GPU Display Driver for Linux contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where a guest VM user may cause an out-of-bounds write by sending a crafted RPC message with invalid performance state list size parameters.
