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-2023-54309 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2023-54309/ (Markdown: https://insights.sbomify.com/CVE-2023-54309/index.md)","id":"CVE-2023-54309","markdown":"https://insights.sbomify.com/CVE-2023-54309/index.md","name":"CVE-2023-54309","record":{"aliases":["BELL-CVE-2023-54309","DEBIAN-CVE-2023-54309","GHSA-gc92-cfvx-57qj","UBUNTU-CVE-2023-54309"],"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 TPM","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel TPM proxy driver allows local attackers to trigger memory corruption, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntpm: tpm_vtpm_proxy: fix a race condition in /dev/vtpmx creation\n\n/dev/vtpmx is made visible before 'workqueue' is initialized, which can\nlead to a memory corruption in the worst case scenario.\n\nAddress this by initializing 'workqueue' as the very first step of the\ndriver initialization.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"tpm: tpm_vtpm_proxy: fix a race condition in /dev/vtpmx creation","id":"CVE-2023-54309","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2023"},"n_packages":0,"n_references":8,"next":{"headline":"scsi: message: mptlan: Fix use after free bug in mptlan_remove() due to race condition","id":"CVE-2023-54310"},"packages":[],"prev":{"headline":"ALSA: ymfpci: Create card with device-managed snd_devm_card_new()","id":"CVE-2023-54308"},"products":["Linux"],"published":"2025-12-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A race condition in the Linux kernel TPM proxy driver allows local attackers to trigger memory corruption, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2023-54309/"}
