(I.e.\ninserting a new inline backref, which means the backref should already\nexist)\n\n[ENHANCEMENT]\nAfter the WARN_ON(), dump all the parameters and the extent tree\nleaf to help debug.","modified":"2026-04-02T09:44:46.052424Z","published":"2025-10-07T15:21:28.975Z","related":["SUSE-SU-2025:21040-1","SUSE-SU-2025:21052-1","SUSE-SU-2025:21056-1","SUSE-SU-2025:21064-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4128-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4140-1","SUSE-SU-2025:4141-1","SUSE-SU-2025:4189-1","SUSE-SU-2025:4301-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53672.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/28062cd6eda04035d8f6ded2001292ac8b496149"},{"type":"WEB","url":"https://git.kernel.org/stable/c/376b41524b71e494514720bd6114325b0a2ed19c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/400e08a16604b534fdd82c5a288fa150d04f5f79"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6994f806c6d1ae8b59344d3700358547f3b3fe1d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7afbfde45d665953b4d5a42a721e15bf0315d89b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f72f50547b7af4ddf985b07fc56600a4deba281"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b7c3cf2f6c42e6688b1c37215a0b1663f982f915"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e70ba449b04b40584bdabb383d10455397cbf177"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53672.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53672"},{"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":"492104c866cb1b62a11393adccb477f5cd2c7768"},{"fixed":"376b41524b71e494514720bd6114325b0a2ed19c"},{"fixed":"400e08a16604b534fdd82c5a288fa150d04f5f79"},{"fixed":"7afbfde45d665953b4d5a42a721e15bf0315d89b"},{"fixed":"b7c3cf2f6c42e6688b1c37215a0b1663f982f915"},{"fixed":"6994f806c6d1ae8b59344d3700358547f3b3fe1d"},{"fixed":"28062cd6eda04035d8f6ded2001292ac8b496149"},{"fixed":"e70ba449b04b40584bdabb383d10455397cbf177"},{"fixed":"7f72f50547b7af4ddf985b07fc56600a4deba281"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53672.json"}}],"schema_version":"1.7.5"}
