To make things simpler, just\ncall debugfs_lookup_and_remove() instead which handles all of the logic\nat once.","modified":"2026-04-02T09:44:01.483841Z","published":"2025-09-17T14:56:38.400Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53346.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/29d53c4c5a6f6d2b93aaac95b65cb4c907faf2ff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2bb3669f576559db273efe49e0e69f82450efbca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94f68f3e059c478e240f65fcb64746fe371295df"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb99db06b8b6ce9351633fc61bec9919d8f6f52b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dd9981a11d74ff2eb253bb5c459876f8bd3c6c36"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6d3aee1c66358471275df9dddd480010f061b0e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53346.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53346"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4b1a29a7f5425d32640b34b8a755f34e02f64d0f"},{"fixed":"f6d3aee1c66358471275df9dddd480010f061b0e"},{"fixed":"dd9981a11d74ff2eb253bb5c459876f8bd3c6c36"},{"fixed":"bb99db06b8b6ce9351633fc61bec9919d8f6f52b"},{"fixed":"29d53c4c5a6f6d2b93aaac95b65cb4c907faf2ff"},{"fixed":"94f68f3e059c478e240f65fcb64746fe371295df"},{"fixed":"2bb3669f576559db273efe49e0e69f82450efbca"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53346.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
