However, the caller ca8210_probe() then calls ca8210_remove(),\nwhere priv->clk is freed again in ca8210_unregister_ext_clock(). In\nthis case, a use-after-free may happen in the second time we call\nclk_unregister().\n\nFix this by removing the first clk_unregister(). Also, priv->clk could\nbe an error code on failure of clk_register_fixed_rate(). Use\nIS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/217efe32a45249eb07dcd7197e8403de98345e66","https://git.kernel.org/stable/c/28b68cba378e3e50a4082b65f262bc4f2c7c2add","https://git.kernel.org/stable/c/55e06850c7894f00d41b767c5f5665459f83f58f","https://git.kernel.org/stable/c/84c6aa0ae5c4dc121f9996bb8fed46c80909d80e","https://git.kernel.org/stable/c/85c2857ef90041f567ce98722c1c342c4d31f4bc"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:46:54.846886191+00:00"},"epss":{"cve":"CVE-2023-52510","score":0.00244,"percentile":0.15684,"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).
