In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
power: supply: lp8727: fix use-after-free in lp8727_release_irq()<\/p>\n
lp8727_isr_func(), the threaded IRQ handler, is the only caller that arms
\npchg->work via schedule_delayed_work(). lp8727_release_irq() currently
\ncancels the work before freeing the IRQ, so an IRQ delivered in between
\ncan re-arm the work through the threaded handler. After .remove returns
\nthe devm layer frees pchg while lp8727_delayed_func() may still run and
\ndereference it.<\/p>\n
Free the IRQ first so the threaded handler is quiesced and can no longer
\nqueue work, then cancel the delayed work to drain the final generation.<\/p>\n
