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-2023-33952 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2023-33952/ (Markdown: https://insights.sbomify.com/CVE-2023-33952/index.md)","id":"CVE-2023-33952","markdown":"https://insights.sbomify.com/CVE-2023-33952/index.md","name":"CVE-2023-33952","record":{"aliases":["AZL-27638","AZL-27756","BELL-CVE-2023-33952","DEBIAN-CVE-2023-33952","GHSA-8f4h-wr7j-w67m","UBUNTU-CVE-2023-33952"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"high_privilege","summary":"A double-free vulnerability in the Linux kernel vmwgfx driver allows local privileged users to escalate privileges and execute code in kernel context.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"linux_kernel","vendor":"linux"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_for_real_time","vendor":"redhat"},{"product":"enterprise_linux_for_real_time_for_nfv","vendor":"redhat"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"A double-free vulnerability was found in handling vmw_buffer_object objects in the vmwgfx driver in the Linux kernel.
