To make things simpler, just\ncall debugfs_lookup_and_remove() instead which handles all of the logic\nat once.","modified":"2026-03-20T12:33:00.086892Z","published":"2025-09-15T14:04:07.411Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53173.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/04a189c720aa2b6091442113ce9b9bc93552dff8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/139769c4bd8273b5e3f85ea474aa37018fe7e436"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4459d1e7bd0421b3b6fcd745773d8823f71615ef"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cf042964c2fa72950bbbf25b2cdd732b873e89db"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53173.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53173"},{"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":"4dec5f1af694526db760dfbb47211236e556e27c"},{"fixed":"cf042964c2fa72950bbbf25b2cdd732b873e89db"},{"fixed":"4459d1e7bd0421b3b6fcd745773d8823f71615ef"},{"fixed":"139769c4bd8273b5e3f85ea474aa37018fe7e436"},{"fixed":"04a189c720aa2b6091442113ce9b9bc93552dff8"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-53173.json"}}],"schema_version":"1.7.5"}
