  "summary": "power: supply: twl4030_charger: cancel workers via devm",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: twl4030_charger: cancel workers via devm\n\nbci is devm-allocated. 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]",
