To make things simpler, just\ncall debugfs_lookup_and_remove() instead which handles all of the logic\nat once.","modified":"2026-04-11T12:46:46.457467Z","published":"2025-09-18T13:58:47.478Z","related":["SUSE-SU-2025:03615-1","SUSE-SU-2025:03628-1","SUSE-SU-2025:3716-1","SUSE-SU-2025:3761-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53409.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/09709a49283f79184c998d6dafcc01590e4d654d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/79ac2b01e033181e21cc84216ace1f4160eb8950"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8deb87b1e810dd558371e88ffd44339fbef27870"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf0fd01c7cc1061fb2cfda3e2044371642108e6c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53409.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53409"},{"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":"c654cea59dbc352fceafddd44893f3523fdcc08e"},{"fixed":"09709a49283f79184c998d6dafcc01590e4d654d"},{"fixed":"79ac2b01e033181e21cc84216ace1f4160eb8950"},{"fixed":"bf0fd01c7cc1061fb2cfda3e2044371642108e6c"},{"fixed":"8deb87b1e810dd558371e88ffd44339fbef27870"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53409.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.13.0"},{"fixed":"5.15.100"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.18"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53409.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"}]}
