Register writes issued between\nprobe() and the first resume (e.g. from DAPM or ALSA control paths)\ntarget unpowered hardware and cause a system hang.\n\nFix this by calling pm_runtime_resume_and_get() immediately after\npm_runtime_enable() to power the hardware up and enable its clocks.\nRelease the reference afterwards with pm_runtime_put() to allow the\nruntime PM framework to suspend the device and switch the regmap to\ncache-only mode when idle.\n\nWhen CONFIG_PM is disabled or runtime PM is not enabled, pm_runtime_*\ncalls are stubs that do not power up the hardware. Handle this case\nexplicitly by calling fsl_audmix_runtime_resume() directly so the\nhardware is always initialised and its clocks are enabled, ensuring\nregister accesses succeed regardless of PM configuration.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/22c944e440bc9b16c4ee409943d69bb8ef575c9e","https://git.kernel.org/stable/c/3359ba93d01a23b2e4249e9e44ccfe48eb9c5d71","https://git.kernel.org/stable/c/b5c3f8015af442c2411722cf8c220cfbae271230","https://git.kernel.org/stable/c/e921cc73fae68ccee932ad0a4fb11d637557db0e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-93184","score":0.00209,"percentile":0.10917,"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).
