This triggers an \"already\ndisabled\" WARN() in the first case and leaks an enable reference in\nthe second, leaving the clock ungateable.\n\nGuard both sides with the existing mclk_flag, as fsl_sai.c does with\nmclk_streams.","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-404"],"references":["https://git.kernel.org/stable/c/470db2026a435b79f7ecb4d65523ea16a99d55d8","https://git.kernel.org/stable/c/d3dbccfe6afa7b9a6a7ed65cfaa76a47fa050a56","https://git.kernel.org/stable/c/fa1bbe3534499dd89d3b0b941d6dd4ddb70c31b5"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-98093","score":0.00127,"percentile":0.02363,"date":"2026-10-25"},"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).
