To make things simpler, just\ncall debugfs_lookup_and_remove() instead which handles all of the logic\nat once.","modified":"2026-04-11T12:46:46.270519Z","published":"2025-09-18T13:33:32.859Z","related":["SUSE-SU-2025:03615-1","SUSE-SU-2025:03628-1","SUSE-SU-2025:3716-1","SUSE-SU-2025:3761-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53390.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/36c893d3a759ae7c91ee7d4871ebfc7504f08c40"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5a7a9efdb193d3c8a35821548a8e99612c358828"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f1e53f88e8babf293ec052b70aa9d2a3554360c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e47e2bf78812adbd73c45c941d3c51add30b58d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53390.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53390"},{"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":"2942df675128b156b0bc8571e2cb2d006fc26e84"},{"fixed":"7f1e53f88e8babf293ec052b70aa9d2a3554360c"},{"fixed":"5a7a9efdb193d3c8a35821548a8e99612c358828"},{"fixed":"8e47e2bf78812adbd73c45c941d3c51add30b58d"},{"fixed":"36c893d3a759ae7c91ee7d4871ebfc7504f08c40"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53390.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-2023-53390.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"}]}
