To make things simpler, just\ncall debugfs_lookup_and_remove() instead which handles all of the logic\nat once.","modified":"2026-04-11T12:46:38.734087Z","published":"2025-03-27T16:37:16.130Z","related":["SUSE-SU-2025:01620-1","SUSE-SU-2025:01640-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52936.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/066ecbf1a53eb0b92b10c8df7808666be6ea5681"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cf1c917bf1c761a557b26410024e90057646c049"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d83d7ed260283560700d4034a80baad46620481b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52936.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52936"},{"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":"69dd4503a7e6bae3389b8e028e5768008be8f2d7"},{"fixed":"066ecbf1a53eb0b92b10c8df7808666be6ea5681"},{"fixed":"cf1c917bf1c761a557b26410024e90057646c049"},{"fixed":"d83d7ed260283560700d4034a80baad46620481b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52936.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.12.0"},{"fixed":"5.15.93"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52936.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"}]}
