Overview\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: max17040: synchronize work cancellation on suspend\n\nmax17040_work() requeues itself after every poll. cancel_delayed_work()\nonly cancels a pending instance and does not wait for a callback that is\nalready running.\n\nIf system suspend races with the polling callback, the callback can\ncontinue accessing the fuel gauge and requeue itself after the suspend\ncallback returns.\n\nUse cancel_delayed_work_sync() to ensure polling is quiesced before\nsuspend completes.\n\n## Affected\n\n- `Linux
