Two workers (bci->work and bci->current_worker)\ndereference it. twl4030_bci_remove() disables charging and masks\ninterrupts. It cancels neither worker. A worker pending at remove() can\nrun after devm frees bci.\n\nThe USB transceiver comes from devm_usb_get_phy_by_node(). devm\nunregisters its notifier only after remove() returns. A cancel_work_sync()\nin remove() can then race a notifier reschedule. devm_work_autocancel()\nand devm_delayed_work_autocancel() avoid that. They cancel the workers\nduring devm release, before bci is freed.\n\nThe current_worker is registered first, since devm will cancel in\nreverse order and bci->work can reschedule current_worker.\n\n[Move comment about order into the commit message]","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/6eba34732524067da2aad5ddfdfbc641ded10e9e","https://git.kernel.org/stable/c/72a2d6cd049f892853e4e2d8d8fc5e7d0244a458","https://git.kernel.org/stable/c/9644c96ef8646c65d46caa5139a6631e29b79d6c","https://git.kernel.org/stable/c/a4460e89d4088cfec2da5be33e265ef1a8e780e9","https://git.kernel.org/stable/c/b955da82db4170bdf1c784dc457287aa0c977378"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89464","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).
