In the Linux kernel, the following vulnerability has been resolved:
usb: typec: qcom-pmic: cancel reset_work on stop
pdphy_stop() disables IRQs but leaves reset_work pending. If the IRQ handler schedules it just before disable_irq(), the work runs after remove() frees the struct via devm.
Call cancel_work_sync() after disabling IRQs to close the window.
This issue was found by an in-house static analysis tool.
