While never actually documented, this is evidenced by the wide\nusage of clk_register and clk_hw_register with a NULL device pointer,\nand the fact that the core of_clk_hw_register() function also passes a\nNULL device pointer.\n\nA call to clk_hw_get_clk() on a clk_hw struct whose clk_core is in that\ncase will result in a NULL pointer derefence when it calls dev_name() on\nthat NULL device pointer.\n\nAdd a test for this case and use NULL as the dev_id if the device\npointer is NULL.","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-476"],"references":["https://git.kernel.org/stable/c/0c1b56df451716ba207bbf59f303473643eee4fd","https://git.kernel.org/stable/c/23f89fe005b105f0dcc55034c13eb89f9b570fac","https://git.kernel.org/stable/c/4be3e4c05d8dd1b83b75652cad88c9e752ec7054","https://git.kernel.org/stable/c/d183f20cf5a7b546d4108e796b98210ceb317579"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49187","score":0.00268,"percentile":0.19033,"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).
