To make things simpler, just\ncall debugfs_lookup_and_remove() instead which handles all of the logic\nat once.","modified":"2026-04-02T09:43:46.826458Z","published":"2025-09-15T14:06:45.301Z","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-2023-53197.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0a3f82c79c86278e7f144564b1cb6cc5c3657144"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9cb88847b8b86f132309030022a23dca895b6f61"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c6af1dbc99ad37bf67c8703982df4d7f12d256c1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e529aeb771aef1402c899b6b405610ef444d5d88"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53197.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53197"},{"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":"5649d86f537887c2be88689986ec4dd493d4babe"},{"fixed":"c6af1dbc99ad37bf67c8703982df4d7f12d256c1"},{"fixed":"e529aeb771aef1402c899b6b405610ef444d5d88"},{"fixed":"9cb88847b8b86f132309030022a23dca895b6f61"},{"fixed":"0a3f82c79c86278e7f144564b1cb6cc5c3657144"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53197.json"}}],"schema_version":"1.7.5"}
