{"id":"CVE-2023-53091","summary":"ext4: update s_journal_inum if it changes after journal replay","details":"In the Linux kernel, the following vulnerability has been resolved:\n\next4: update s_journal_inum if it changes after journal replay\n\nWhen mounting a crafted ext4 image, s_journal_inum may change after journal\nreplay, which is obviously unreasonable because we have successfully loaded\nand replayed the journal through the old s_journal_inum. And the new\ns_journal_inum bypasses some of the checks in ext4_get_journal(), which\nmay trigger a null pointer dereference problem. So if s_journal_inum\nchanges after the journal replay, we ignore the change, and rewrite the\ncurrent journal_inum to the superblock.","modified":"2026-04-03T13:14:39.347947Z","published":"2025-05-02T15:55:36.852Z","related":["SUSE-SU-2025:01918-1","SUSE-SU-2025:01966-1","SUSE-SU-2025:02173-1","SUSE-SU-2025:02262-1","SUSE-SU-2025:02334-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53091.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3039d8b8692408438a618fac2776b629852663c3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/499fef2030fb754c68b1c7cb3a799a3bc1d0d925"},{"type":"WEB","url":"https://git.kernel.org/stable/c/70e66bdeae4d0f7c8e87762f425b68aedd5e8955"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ee0c5277d4fab920bd31345c49e193ecede9ecef"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53091.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53091"},{"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":"345c0dbf3a30872d9b204db96b5857cd00808cae"},{"fixed":"499fef2030fb754c68b1c7cb3a799a3bc1d0d925"},{"fixed":"70e66bdeae4d0f7c8e87762f425b68aedd5e8955"},{"fixed":"ee0c5277d4fab920bd31345c49e193ecede9ecef"},{"fixed":"3039d8b8692408438a618fac2776b629852663c3"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"51890201da4d654f6ca131bc45a0e892bb10de1d"},{"last_affected":"7eff961ca9f364be255d279346517ba0158ec8e3"},{"last_affected":"a9855260fe8d8680bf8c4f0d8303b696c861e99b"},{"last_affected":"795762468125a6412c089651e74f780bee154118"},{"last_affected":"2fd4629de51974002f4e9cf1a35a1926dd6c9d99"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53091.json"}}],"schema_version":"1.7.5"}
