The reset devm action only unregisters\nthe notifier and was registered before the power supplies, so devm frees\nbq->charger on unwind before the action runs; a usb_work still queued can\nthen dereference it.\n\nRegister the reset action after the power supplies, so it unregisters\nthe notifiers and drains usb_work before the supplies are released.\nInitialize usb_work and obtain the PHY references before registering\nthe notifiers, so the worker cannot run before the supplies exist.\n\nFound by static analysis.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2cfb59dc9df8b5ebdd95e3d874a7f4690cee2bc8","https://git.kernel.org/stable/c/2dd6cd823777bea6d9a880a12a92a73ec76aee0b","https://git.kernel.org/stable/c/9a467bd1e6811011026ad4c8de701b940d88a00c","https://git.kernel.org/stable/c/9dcfdf6c598301b278f0b3490eb2bf4f600524e2","https://git.kernel.org/stable/c/9e1aba34df9a87d53460888e05718717c0f69343"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89474","score":0.00173,"percentile":0.06635,"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).
