The caller must decrement the reference count by\ncalling pci_dev_put().\n\nSince 'dma_dev' is only used to filter the channel in filter(), we can\ncall pci_dev_put() before exiting from pch_request_dma(). Add the\nmissing pci_dev_put() for the normal and error path.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/07f4ca68b0f6bf84b6b391c14b59fd179fcde9c5","https://git.kernel.org/stable/c/4f5d28865c665c9064de631a518f9bc8099d9ce4","https://git.kernel.org/stable/c/516614a371c26e3334625b4bca19a5362bf658d6","https://git.kernel.org/stable/c/56e5a7c5ee3f0dc8978b5df2b1a98a1b060c5e2a","https://git.kernel.org/stable/c/6f7d82380fbeaed3a940efc33c23f0c4bbd0fc02"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:12:35.277909958+00:00"},"epss":{"cve":"CVE-2022-50576","score":0.00249,"percentile":0.16224,"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).
