An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-7240 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2019-7240/ (Markdown: https://insights.sbomify.com/CVE-2019-7240/index.md)","id":"CVE-2019-7240","markdown":"https://insights.sbomify.com/CVE-2019-7240/index.md","name":"CVE-2019-7240","record":{"aliases":["GHSA-qr76-rqwf-r4c5"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"System monitoring driver","requires_auth":"high_privilege","summary":"A vulnerability in the WinRing0x64.sys driver allows arbitrary MSR writes via IOCTL, enabling Ring-0 code execution and privilege escalation.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"system_monitor","vendor":"moo0"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-665","name":"Improper Initialization"}],"description":"An issue was discovered in WinRing0x64.sys in Moo0 System Monitor 1.83.
