CyberRota Analysis

AI-Generated

The vulnerability affects the Linux kernel's handling of the max17040 fuel gauge driver, where improper synchronization during system suspend can allow a polling callback to continue executing and requeue itself. This can lead to potential race conditions, resulting in inconsistent state or data corruption. Organizations using Linux systems with this driver should prioritize patching to mitigate risks associated with unexpected behavior during power management operations.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: power: supply: max17040: synchronize work cancellation on suspend max17040_work() requeues itself after every poll. cancel_delayed_work() only cancels a pending instance and does not wait for a callback that is already running. If system suspend races with the polling callback, the callback can continue accessing the fuel gauge and requeue itself after the suspend callback returns. Use cancel_delayed_work_sync() to ensure polling is quiesced before suspend completes.
