When pvr2_hdw_create returns back to pvr2_context_create,\nit calls pvr2_context_destroy to destroy context, but mp->hdw is NULL,\nwhich leads to that pvr2_hdw_destroy directly returns.\n\nFix this by adding v4l2_device_unregister to decrease the refcount of\nusb interface.","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":["CWE-401"],"references":["https://git.kernel.org/stable/c/2fe46195d2f0d5d09ea65433aefe47a4d0d0ff4d","https://git.kernel.org/stable/c/466b67c0543b2ae67814d053f6e29b39be6b33bb","https://git.kernel.org/stable/c/491762b3250fb06a0c97b5198656ea48359eaeed","https://git.kernel.org/stable/c/945a9a8e448b65bec055d37eba58f711b39f66f0","https://git.kernel.org/stable/c/ba7dd8a9686a61a34b3a7b922ce721378d4740d0"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2022-49982","score":0.00253,"percentile":0.16892,"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).
