{"id":"CVE-2024-39472","summary":"xfs: fix log recovery buffer allocation for the legacy h_size fixup","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: fix log recovery buffer allocation for the legacy h_size fixup\n\nCommit a70f9fe52daa (\"xfs: detect and handle invalid iclog size set by\nmkfs\") added a fixup for incorrect h_size values used for the initial\numount record in old xfsprogs versions.  Later commit 0c771b99d6c9\n(\"xfs: clean up calculation of LR header blocks\") cleaned up the log\nreover buffer calculation, but stoped using the fixed up h_size value\nto size the log recovery buffer, which can lead to an out of bounds\naccess when the incorrect h_size does not come from the old mkfs\ntool, but a fuzzer.\n\nFix this by open coding xlog_logrec_hblks and taking the fixed h_size\ninto account for this calculation.","modified":"2026-04-02T12:17:00.219875Z","published":"2024-07-05T06:42:03.495Z","related":["ALSA-2024:8617","SUSE-SU-2024:2802-1","SUSE-SU-2024:2894-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2939-1","SUSE-SU-2024:2947-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/39xxx/CVE-2024-39472.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/45cf976008ddef4a9c9a30310c9b4fb2a9a6602a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/57835c0e7152e36b03875dd6c56dfeed685c1b1f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2389c074973aa94e34992e7f66dac0de37595b5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f754591b17d0ee91c2b45fe9509d0cdc420527cb"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/39xxx/CVE-2024-39472.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-39472"},{"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":"0c771b99d6c9a0552fea5cc43669b726dad8f659"},{"fixed":"f754591b17d0ee91c2b45fe9509d0cdc420527cb"},{"fixed":"57835c0e7152e36b03875dd6c56dfeed685c1b1f"},{"fixed":"c2389c074973aa94e34992e7f66dac0de37595b5"},{"fixed":"45cf976008ddef4a9c9a30310c9b4fb2a9a6602a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-39472.json"}}],"schema_version":"1.7.5"}
