{"id":"AZL-89046","summary":"CVE-2026-46161 affecting package kernel for versions less than 6.6.141.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid10: fix divide-by-zero in setup_geo() with zero far_copies\n\nsetup_geo() extracts near_copies (nc) and far_copies (fc) from the\nuser-provided layout parameter without checking for zero. When fc=0\nwith the \"improved\" far set layout selected, 'geo-\u003efar_set_size =\ndisks / fc' triggers a divide-by-zero.\n\nValidate nc and fc immediately after extraction, returning -1 if\neither is zero.","modified":"2026-08-28T17:47:53.120907480Z","published":"2026-05-28T10:16:31Z","upstream":["CVE-2026-46161"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46161"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-89046.json"}}],"schema_version":"1.9.0"}
