This leads to an oops when .allow_link fails or\nwhen .drop_link is performed. Remove the helper.\n\nAlso drop pci_epc_put(). EPC device refcounting is tied to configfs EPC\ngroup lifetime, and pci_epc_put() in the .drop_link path is sufficient.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/3446beddba450c8d6f9aca2f028712ac527fead3","https://git.kernel.org/stable/c/65fc57c8b8f0b31be62be291cb1bb01755cec85d","https://git.kernel.org/stable/c/72099f015d3c77bf2eb703d1aab113bd7a60915a","https://git.kernel.org/stable/c/756ca5e7ed22d9045bb4de4c981f9149278d5cd3","https://git.kernel.org/stable/c/c3029721b84f59e790285ad27544ed5d3cb0f2a6"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-46009","score":0.00123,"percentile":0.02024,"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).
