Summary
power: supply: lp8727: fix use-after-free in lp8727_release_irq()
Details

In the Linux kernel, the following vulnerability has been resolved:

power: supply: lp8727: fix use-after-free in lp8727_release_irq()

lp8727_isr_func(), the threaded IRQ handler, is the only caller that arms pchg->work via schedule_delayed_work(). lp8727_release_irq() currently cancels the work before freeing the IRQ, so an IRQ delivered in between can re-arm the work through the threaded handler. After .remove returns the devm layer frees pchg while lp8727_delayed_func() may still run and dereference it.

Free the IRQ first so the threaded handler is quiesced and can no longer queue work, then cancel the delayed work to drain the final generation.

This issue was found by an in-house static analysis tool.
