  "details": "In the Linux kernel, the following vulnerability has been resolved:  power: supply: twl4030_charger: cancel workers via devm  bci is devm-allocated. Two workers (bci-\u003ework and bci-\u003ecurrent_worker) dereference it. twl4030_bci_remove() disables charging and masks interrupts. It cancels neither worker. A worker pending at remove() can run after devm frees bci.  The USB transceiver comes from devm_usb_get_phy_by_node(). devm unregisters its notifier only after remove() returns. A cancel_work_sync() in remove() can then race a notifier reschedule. devm_work_autocancel() and devm_delayed_work_autocancel() avoid that. They cancel the workers during devm release, before bci is freed.  The current_worker is registered first, since devm will cancel in reverse order and bci-\u003ework can reschedule current_worker.
