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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/19ef775c91c6bf4bd2b60f6616f4e28b621cdd6a","https://git.kernel.org/stable/c/54f905821f26d385fba407a920b51f0a752c76dc","https://git.kernel.org/stable/c/90d9f3ef28843e6c35149324b8eefb427a7435c2","https://git.kernel.org/stable/c/ab0eec0ff0a421737a37f510ceab5c6ea59cd05a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68319","score":0.00168,"percentile":0.06064,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
