CVE-2026-89464

Estado: RecibidaSin puntuar—

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->work and bci->current_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->work can reschedule current_worker.
