It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-32629 exists.\n\nAffected product: Canonical Ubuntu 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-2023-32629/ (Markdown: https://insights.sbomify.com/CVE-2023-32629/index.md)","id":"CVE-2023-32629","markdown":"https://insights.sbomify.com/CVE-2023-32629/index.md","name":"CVE-2023-32629","record":{"aliases":["GHSA-5xvw-32xh-2vr5"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ubuntu Kernel","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges in Ubuntu kernels due to missing permission checks in overlayfs metadata copying.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"ubuntu_linux","vendor":"canonical"}],"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-863","name":"Incorrect Authorization"}],"description":"Local privilege escalation vulnerability in Ubuntu Kernels overlayfs ovl_copy_up_meta_inode_data skip permission checks when calling ovl_do_setxattr on Ubuntu kernels","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-07-26","github_poc":5,"max_poc_stars":109,"metasploit":1,"nuclei":0,"refs":[{"date":"2023-11-09T09:19:23Z","kind":"github_poc","ref":"https://github.com/ThrynSec/CVE-2023-32629-CVE-2023-2640---POC-Escalation","stars":109,"title":"Ubuntu Privilege Escalation bash one-liner using CVE-2023-32629 \u0026 CVE-2023-2640"},{"date":"2023-08-11T21:08:38Z","kind":"github_poc","ref":"https://github.com/kaotickj/Check-for-CVE-2023-32629-GameOver-lay","stars":10,"title":"Check for CVE-2023-32629 \"GameOver(lay)\" vulnerability "},{"date":"2023-11-11T14:33:38Z","kind":"github_poc","ref":"https://github.com/k4but0/Ubuntu-LPE","stars":4,"title":"One-Liner CVE-2023-32629/CVE-2023-2640 Ubuntu Privilege Escalation"},{"date":"2023-12-13T19:33:38Z","kind":"github_poc","ref":"https://github.com/xS9NTX/CVE-2023-32629-CVE-2023-2640-Ubuntu-Privilege-Escalation-POC","stars":1,"title":"CVE-2023-32629 \u0026 CVE-2023-2640  Ubuntu Privilege Escalation POC"},{"date":"2023-07-26","kind":"metasploit","ref":"exploit/linux/local/gameoverlay_privesc","stars":null,"title":"GameOver(lay) Privilege Escalation and Container Escape"},{"date":"2026-04-25T14:42:57Z","kind":"github_poc","ref":"https://github.com/h3raklez/CVE-2023-32629","stars":0,"title":"OverlayFS Local Privilege Escalation -
