In this case, resubmitting the bio can lead to a deadlock\nif the array is suspended before md_handle_request() acquires an\nactive_io reference via percpu_ref_tryget_live().\n\nSince the cloned bio already holds an active_io reference,\ntrying to acquire another reference via percpu_ref_tryget_live()\ncan lead to a deadlock while the array is suspended.\n\nFix this by using percpu_ref_get() for md cloned bios.","modified":"2026-08-31T05:26:27Z","published":"2026-08-15T06:22:39Z","upstream":["CVE-2026-74375"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74375"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96420.json"}}],"schema_version":"1.9.0"}
