  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: bq24257: fix use-after-free on remove\n\nThe STAT-pin interrupt is devm-managed, so it stays armed until the devm\ncleanup that runs after remove() returns. remove() cancels\nbq->iilimit_setup_work while the threaded handler can still fire; that\nhandler reschedules the work and dereferences bq, so the work runs\nagainst freed memory once devm frees bq.\n\nMake the delayed work device-managed with devm_delayed_work_autocancel(),\nregistered before the interrupt request. The devm cleanup then releases\nthe interrupt first, so the handler can no longer reschedule the work,\nand cancels the work before bq is freed. The explicit\ncancel_delayed_work_sync() in remove() is no longer needed and is dropped.\n\nFound by static analysis.",
