The comment of\npci_get_device() says that it will increase the reference count for the\nreturned pci_dev and also decrease the reference count for the input\npci_dev @from if it is not NULL.\n\nIf we break for_each_pci_dev() loop with pdev not NULL, we need to call\npci_dev_put() to decrease the reference count. We add a new struct\n'amd_geode_priv' to record pointer of the pci_dev and membase, and then\nadd missing pci_dev_put() for the normal and error path.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/19b7b85773b18457ff85a9ff4f5e2a2d4bf7ed0c","https://git.kernel.org/stable/c/5cc818ad53df650cac8fb41d9066665366af3f03","https://git.kernel.org/stable/c/6b9e43c4098f1310f5b4d52121d007a219fa5d43","https://git.kernel.org/stable/c/82bd423ed977847652b2048b0f8dcf049b1847a9","https://git.kernel.org/stable/c/874f798c2db5ad595e46982d7f727a679dacb048"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2022-50659","score":0.00276,"percentile":0.20103,"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).
