To meet this requirement, this device is added to genpd\nto control ISP power using runtime PM. The pm_runtime_get_sync() called\nbefore i2c_dw_probe() triggers PM resume, which powers on ISP and also\ninvokes the amdisp i2c runtime resume before the probe completes resulting\nin this race condition and a NULL dereferencing issue in v7.0\n\nFix this race condition by using the genpd APIs directly during probe:\n  - Call dev_pm_genpd_resume() to Power ON ISP before probe\n  - Call dev_pm_genpd_suspend() to Power OFF ISP after probe\n  - Set the device to suspended state with pm_runtime_set_suspended()\n  - Enable runtime PM only after the device is fully initialized","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/83bcea9da91965484df64a6492b89e65d41ab31c","https://git.kernel.org/stable/c/e2f1ada8e089dd5a331bcd8b88125ae2af8d188f","https://git.kernel.org/stable/c/e81f0341754c309e33babea2821eda8f98f0b44c"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-31572","score":0.00088,"percentile":0.00348,"date":"2026-11-01"},"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).
