{"id":"AZL-48045","summary":"CVE-2024-43828 affecting package kernel for versions less than 6.6.47.1-1","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":"2026-04-01T05:16:00.110233Z","published":"2024-08-17T10:15:08Z","upstream":["CVE-2024-43828"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-43828"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.47.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-48045.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
