To make things simpler, just\ncall debugfs_lookup_and_remove() instead which handles all of the logic\nat once.","modified":"2026-04-02T09:44:08.368475Z","published":"2025-09-18T13:58:45.968Z","related":["SUSE-SU-2026:0474-1","SUSE-SU-2026:0496-1","SUSE-SU-2026:0617-1","SUSE-SU-2026:1131-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53407.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/67c931a3f2f061bf457995fd21fff114325e0c30"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a6952fa0366d4408eb8695af1a0578c39ec718a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8da78a60f3323ce7aac589d49fb82f71a04bc835"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b14d188d0d0b86e2180525aefd570dbb6ebd6aa9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53407.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53407"},{"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":"8efd88f946017b69af67931a133b6dce92c27fd0"},{"fixed":"8da78a60f3323ce7aac589d49fb82f71a04bc835"},{"fixed":"b14d188d0d0b86e2180525aefd570dbb6ebd6aa9"},{"fixed":"67c931a3f2f061bf457995fd21fff114325e0c30"},{"fixed":"7a6952fa0366d4408eb8695af1a0578c39ec718a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53407.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"}]}
