For this bug, jbd2_journal_restart() is\ncalled by ocfs2_split_extent() during defragmenting.\n\nHow to fix\n\nFor ocfs2_split_extent() can handle journal operations totally by itself. \nCaller doesn't need to call journal access/dirty pair, and caller only\nneeds to call journal start/stop pair.  The fix method is to remove\njournal access/dirty from __ocfs2_move_extent().\n\nThe discussion for this patch:\nhttps://oss.oracle.com/pipermail/ocfs2-devel/2023-February/000647.html","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"8f603e567aa7a243e68ca48b4f105b990851360f"},{"fixed":"5f43d34a51ed30e6a60f7e59d224a63014fe2cd5"},{"fixed":"7f3b1c28e2908755fb248d3ee8ff56826f2387db"},{"fixed":"669134a66d37258e1c4a5cfbd5b82f547ae30fca"},{"fixed":"2c559b3ba8e0b9e3c4bb08159a28ccadc698410f"},{"fixed":"33665d1042666f2e5c736a3df1f453e31f030663"},{"fixed":"8163ea90d89b7012dd1fa4b28edf5db0c641eca7"},{"fixed":"590507ebabd33cd93324c04f9a5538309a5ba934"},{"fixed":"60eed1e3d45045623e46944ebc7c42c30a4350f0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53564.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"4.14.308"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.19.276"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.235"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.173"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.99"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.2.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53564.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2c559b3ba8e0b9e3c4bb08159a28ccadc698410f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/33665d1042666f2e5c736a3df1f453e31f030663"},{"type":"WEB","url":"https://git.kernel.org/stable/c/590507ebabd33cd93324c04f9a5538309a5ba934"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5f43d34a51ed30e6a60f7e59d224a63014fe2cd5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/60eed1e3d45045623e46944ebc7c42c30a4350f0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/669134a66d37258e1c4a5cfbd5b82f547ae30fca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f3b1c28e2908755fb248d3ee8ff56826f2387db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8163ea90d89b7012dd1fa4b28edf5db0c641eca7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53564.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53564"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53564.json"}}
