This avoids the deadlock while also ensuring proper\nconfig space access serialization during the reset.\n\nThe pci_dev_get/put calls are also removed as they were unnecessary -\nthe driver-owned workqueue is destroyed in pdsc_remove(), guaranteeing\nthe work completes before remove returns. The PCI core holds its\nreference to pci_dev throughout the entire unbind sequence.","published":"2026-08-10T13:20:22.000Z","lastModified":"2026-08-17T05:18:35.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00168,"percentile":0.06023,"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.
