CVE-2026-89461

power: supply: max17040: synchronize work cancellation on suspend

State: Published
Severity: Not scored
Published: Sep 11, 2026
Updated: Oct 19, 2026
Reserved: Sep 11, 2026

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.
