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.","published":"2026-08-15T06:22:39.000Z","lastModified":"2026-10-21T13:19:43.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00168,"percentile":0.06055,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
