{"id":"CVE-2023-52569","summary":"btrfs: remove BUG() after failure to insert delayed dir index item","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: remove BUG() after failure to insert delayed dir index item\n\nInstead of calling BUG() when we fail to insert a delayed dir index item\ninto the delayed node's tree, we can just release all the resources we\nhave allocated/acquired before and return the error to the caller. This is\nfine because all existing call chains undo anything they have done before\ncalling btrfs_insert_delayed_dir_index() or BUG_ON (when creating pending\nsnapshots in the transaction commit path).\n\nSo remove the BUG() call and do proper error handling.\n\nThis relates to a syzbot report linked below, but does not fix it because\nit only prevents hitting a BUG(), it does not fix the issue where somehow\nwe attempt to use twice the same index number for different index items.","modified":"2026-04-11T12:46:32.684814Z","published":"2024-03-02T21:59:40.081Z","related":["SUSE-SU-2024:0856-1","SUSE-SU-2024:0857-1","SUSE-SU-2024:0926-1","SUSE-SU-2024:1320-1","SUSE-SU-2024:1321-1","SUSE-SU-2024:1466-1","SUSE-SU-2024:1480-1","SUSE-SU-2024:1490-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52569.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2c58c3931ede7cd08cbecf1f1a4acaf0a04a41a9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/39c4a9522db0072570d602e9b365119e17fb9f4f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d10fd53393cc5de4b9cf1a4b8f9984f0a037aa51"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52569.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52569"},{"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":"9b378f6ad48cfa195ed868db9123c09ee7ec5ea2"},{"fixed":"d10fd53393cc5de4b9cf1a4b8f9984f0a037aa51"},{"fixed":"2c58c3931ede7cd08cbecf1f1a4acaf0a04a41a9"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"79cf35e16dd5b8639909d4df957503b84de30406"},{"last_affected":"5441532ffc9c8c9f7cab0f8722e6d60a0b5e1259"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52569.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.5.0"},{"fixed":"6.5.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52569.json"}}],"schema_version":"1.7.5"}
