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. (NVD)
