{"id":"CVE-2024-43828","summary":"ext4: fix infinite loop when replaying fast_commit","details":"In the Linux kernel, the following vulnerability has been resolved:\n\next4: fix infinite loop when replaying fast_commit\n\nWhen doing fast_commit replay an infinite loop may occur due to an\nuninitialized extent_status struct.  ext4_ext_determine_insert_hole() does\nnot detect the replay and calls ext4_es_find_extent_range(), which will\nreturn immediately without initializing the 'es' variable.\n\nBecause 'es' contains garbage, an integer overflow may happen causing an\ninfinite loop in this function, easily reproducible using fstest generic/039.\n\nThis commit fixes this issue by unconditionally initializing the structure\nin function ext4_es_find_extent_range().\n\nThanks to Zhang Yi, for figuring out the real problem!","modified":"2026-05-18T05:58:57.749055764Z","published":"2024-08-17T09:21:47.429Z","related":["SUSE-SU-2024:3551-1","SUSE-SU-2024:3561-1","SUSE-SU-2024:3564-1","SUSE-SU-2024:3569-1","SUSE-SU-2024:3587-1","SUSE-SU-2024:3592-1","SUSE-SU-2025:20073-1","SUSE-SU-2025:20077-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/43xxx/CVE-2024-43828.json"},"references":[{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/html/ssa-265688.html"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0619f7750f2b178a1309808832ab20d85e0ad121"},{"type":"WEB","url":"https://git.kernel.org/stable/c/181e63cd595c688194e07332f9944b3a63193de2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ed0496e383cb6de120e56991385dce70bbb87c1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/81f819c537d29932e4b9267f02411cbc8b355178"},{"type":"WEB","url":"https://git.kernel.org/stable/c/907c3fe532253a6ef4eb9c4d67efb71fab58c706"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c6e67df64783e99a657ef2b8c834ba2bf54c539c"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/10/msg00003.html"},{"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/2024/43xxx/CVE-2024-43828.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-43828"},{"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":"8016e29f4362e285f0f7e38fadc61a5b7bdfdfa2"},{"fixed":"5ed0496e383cb6de120e56991385dce70bbb87c1"},{"fixed":"0619f7750f2b178a1309808832ab20d85e0ad121"},{"fixed":"181e63cd595c688194e07332f9944b3a63193de2"},{"fixed":"c6e67df64783e99a657ef2b8c834ba2bf54c539c"},{"fixed":"81f819c537d29932e4b9267f02411cbc8b355178"},{"fixed":"907c3fe532253a6ef4eb9c4d67efb71fab58c706"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-43828.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.0"},{"fixed":"5.10.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.165"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.103"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.44"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.10.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-43828.json"}}],"schema_version":"1.7.5"}
